Stop overthinking it is right. And your three goals from the other thread? Geez, it's not as if you have any real problems if those are the options you have to pursue -- you are already ahead of 95% of people, and probably more than 99% of the people who started out where you are.
The only issue that I see of yours is that you are constantly discussing inferiority in some way; position, social life, athleticism. You know what? you're probably not The Most Interesting and Accomplished Man in the World. And that's actually OK. It's OK to have failed at various aspects of different stuff. It's OK to have missed stuff along the way, hell, I dropped out of high school and grad school because of family medical issues, went to a school where I drove my grandfather's car that my father and I got going after having sat in storage for 15 years when everyone else was in new BMW's / Audis / Mercs, etc. I never went on a date in college because I wasn't the sharpest tool in the box and had to work hard to get where I wanted to go; I also commuted so that I could help out with my family's healthcare needs.
I had a crisis moment, too, when I dropped out of grad school -- the solution for me was figuring out 1) what aspects of my past were driving my outlook in ways that were not helpful or reasonable, 2) what I really wanted, and 3) what course of action would as efficiently as possible give me the possibilities to attain those goals. I started by taking a Myers-Briggs which I found really useful, also talked to people I really respected (one old Prof of mine, for instance), etc. I also learned to stop comparing myself to others -- my issue was not so much that I felt inferior, I just felt behind. So I set out my goals and am measuring my success relative to....wait for it...what I actually care about. The rest of it is bullshit.
Also, to the jackasses who say that life ends after 30 -- fuck 'em. My crisis was around 26-27 or so, and 29-30 were two of my greatest years to date. The young always criticize the old (you die after 30, after 40, after 45, etc), and the old always criticize the young ("youth is wasted on the young"). It's all bullshit, because each set criticizes the other for what they don't have -- the young mock the old for their lack of the accoutrement of youth; the old criticize the young for their lack of wisdom. Guess what, you can't be in both places at once.
