I'm not going to tell you anything about Tao because I really don't know anything about it. But I understand this idea of regrets especially going through those college years. What I've found out after the whole schooling was said and done, is that I had many doubts about similar things, many of which sound incredibly foolish later on. I worried about not having an army of friends, not getting drunk and high and reckless enough, not living the young persons life, not laying with many others because I chose to have a girlfriend, not studying hard enough or not going after a subject I wanted. While I would implore you to go after these things if you want them, you will always find others who wished they went the other way, who got to walk a different path, who harbored regrets.
I had a hard time because I thought I should have many friends, even if I felt more reward discussing pseudo philosophical subjects with a few trusted comrades. I wanted to see my oats, 'learn' what it's like to be a young man by hearing a hundred different moans, even though I found one girl who could show me a thousand herself. These are only a few, but it's easy to look out and feel less than, dysfunctional, subpar, incapable, trapped. College isn't formulaic, it is not the messiah you heard of and hear of then and now. It is not the best years of your life, those don't exist. College is a place you are in at this moment, it's nothing more. It's not a popular opinion but I don't think you get to choose your friends. I think you happen onto them. As an active method, you seem to have the right track by putting yourself out there. But are you letting yourself be there? Or are you trapped hoping THIS conversation will create a future that doesn't exist?
I talked with a man in his 60s who told me he never really had too many life long friends. He made some in high school and they faded in college. He made some in college and he kept up with one of them. He made some in his 20s, then 30s, then on and on. I think we expect too much from higher education. I'm not saying don't go out and look for these people, but expectations can make it difficult to stay grounded, to stay present. Do what you want to do, but don't forget to be there when you do.
I think about being with my girlfriend and how things would have been different in college had I not gone that route. It was only many years later that I realized I'd be in the same spot. Sure without her I'd probably be more open, more social, more 'experienced' and what not. But I wouldn't be as patient, not nearly as grounded, not as focused or loving. Down that road not traveled is a dissipated version of myself, like a calm fag covering a plain. And that's great, but so is what I am now, just a small packed geode glimmering in the dirt.
Go out and casually ask a frisbee bro "hey...how do you throw a hammer like that? I seriously can't figure it out." He'll probably give you a pointer. Maybe he'll scoff at you. Maybe you'll be besties or maybe you'll never see him again. Smile at that, regardless of the outcome. Remember the vinegar tasters. College is a fun time, you get to learn so much. Go to a club fair. Bullshit with the guys at the robotics table. Laugh at the bad jokes at the comedy table. Ask the car dudes if anyone is selling a 65 barracuda in mustard yellow (and get back to me).
I think others are giving you good advice for the anxiety, but realized you can never rid yourself of it completely. But you can let yourself experience it. Not every night out will suck, not every lunch will taste great, not every assignment will go well, but many of them will. You'll join a club and next thing you know some dude is telling you what the meaning of gold is based off his weird skewed reading of the Gita. Best friend for life? Who knows, but I bet it'll feel good then. Remember beers and sex are great and all, but sometimes friends last for a few minutes and sometimes a few years. Be there and enjoy it no matter how it makes you feel. That's the best lesson you can learn in college. Also beware of Internet rants, they make you feel stupid for writing them.
Also take better notes, you won't be able to read those shits in five years time.
