You guys know that you're my favorite assholes, right? OK cool, so there are couple of things that I want you to hear from me. We often have doubts about our decisions, and what we should do next. A wrong choice may often lead to having regrets, and we often feel like we should've done more or less in the past. Well fuck that, this is how I do it, and it's worked just fine for me. For now.
I believe that if you do something with a good intention, even if it's a bad decision, it'll end up working out for the best. In fact, it has always worked out for the best for me. "Learn from your mistakes" is the shit that we hear on the regular, but it's a good saying nonetheless. Mistakes should be considered as wake-up calls, and as you know wake-up calls are a good thing. Whenever you feel like: "I'd like to be in the past right now, given what I know now, I could do so much better and so much more, and I'd be the shit when the current year comes around". I'm sorry but this is kind of a bullshit. Think about what you have now (be it your new cellphone, a new Eminem album, or something as important as a kid) and see if you could do without it. Imagine if you had to take all those exams in school all over again, and ish like that. I bet you won't be up for it, because you've already paid your dues for what you have.
As Chris Rock said for sex, when a man gets a special treatment in bed, he doesn't want to regress from there. If his previous girl sucked his dick 3 times a day, he expects all the other girls from now on to suck his dick 3 times a day. Also, if you didn't want to do something last Friday night, and now you regret it, you should remember that perhaps you didn't feel like going to that party, and if you went in such mood, you probably wouldn't have had a good time (as opposed to the present, when you do feel like going to such party).
Before I signed up for the college where I study now, I spent one year at a different college (it's the same facility, but a different section) and everybody I've told about it, has said: "Why did you go there in the first place, you wasted a year, lost money etc.". Well you know what? I don't regret it one bit. In fact, I'd do it 10 more times if I had to. What I gained from that is more valuable than money. I got to meet wonderful friends in that college, and I would've studied with completely different people if I went to my current college in the first place. The people I'm with now are great, and I'm very happy that I got to spent these years with them. I wouldn't have had nearly as good as time here if I signed up one year earlier.
So when you look at some "bad decisions", think about the good that came out if it, and you'll notice that it outweights the bad things. So whatever you feel like doing, and if it doesn't affect your health (be it drugs or developing a habit of smoking), my advice is to go for it, and don't look back because it'll work out for the best. That's not to say to not be ambitious, which leads to my next point.
If you ever feel that somebody is doing better than you, have in mind that there's at least one thing that you're better at than them. Nobody is better than everybody at everything. Whatever you love the most, my suggestion is to work on becoming the best you can at it, and not to get discouraged. If other people could do it, you can do it too, that's a fact. Maybe you won't be the best at it, but it will separate you from most people. If you become good at at least one thing, it'll give you confidence and people will respect you for it. They may not like you, but the fact that you're vastly better than them at something will probably scare them, and they may feel like they're being left behind. And remember that the worst outcome of trying something new is to be in the same position that you're at now. There's nothing to lose, and at least you'll know that you've tried.
Most of us in here are young, so keep in mind that there's a whole life in front of us. Our minds are capable of great things, and given that we become better/smarter all the time, if you feel that you aren't good enough at what you do; just comfort yourself with your future self. Imagine that your future self will be laughing at your current "stupidity", just as you're laughing at your past self right now, and that should motivate you to keep on going. Have patience and good things will come.
Work the fuck out. If you aren't working out as of now, start immediately. Getting in physical shape is the easiest thing in the world. If there's one thing that guarantees you success - it's working out. Now I'm not saying that you'll be looking like an athlete anytime soon, but you'll sure as hell look better than you do right now. And you don't need to go to a gym, I don't either. But there are simple exercises that can be done in your home. I suggest these ones - http://www.youtube.com/watch?v=vKT9ftn-O5E . As for your diet, just don't eat after 19 o'clock, eat 5 times a day (an apple counts as a meal) because that way your metabolism will be working (burning calories) all the time, and it won't store any fat in your body. Also drink plenty of water, and don't drink coke and things like that. Take it easy with the alcohol as well. Oh and, sprinting is better than jogging across three different area codes.
Set goals, and unless you're having health problems or something important comes up - go and do the fucking goal. I don't care if you said that you're going to dunk a basketball on Saturday, when Saturday comes - go and fucking dunk the ball. Setting minor but achievable goals and doing them will increase your confidence, and you'll be getting more successful at what you do. Your progress will be faster. Set new goals all the time, and always try to do better and more than the last time. Never get too comfortable - Never.
Stay true to your beliefs, and stand by your principles. Everybody is unique and people should appreciate you for who you are. Stick with those people, and always remember that people (good people) do exist. If a girl fucks you over, that's HER problem, not yours. As long as you're a good person, that's what matters the most, and if somebody doesn't treat others like they want to be treated themselves, than it is THEIR fault. So yeah, I'll end this with Robin Williams' saying from Good Will Hunting - "It's not your fault".
