wtf?
Quarter life crisis?
GTFO. Dude, get out there, have as much fun as possible. Your future will be here soon enough, without you wasting the present worrying about it.
All the choices you are making now? If you fuck them up? You can change them!
Unless you have a burning desire to be a doctor or a fighter pilot or something where there is a 15 year training period, it really doesn't matter too much.
I changed degrees twice. I changed careers twice. I'm not even 35, and my life so far has been a complete blast. I'll probably change direction again in 7-8 years once I've made enough cash not to have to work any more and do a PhD.
