/sci/ - Science & Math

What are the best things to do to increase baseline testosterone and IQ / executive function? My anecdotal evidence, which I trust above all, suggest that lots of math/problem solving, fasting, reading (and avoiding scrolling), adequate high quality sleep and exercise are totally yuge here. Also it's sort of nebulous but in general keeping a tidy environment and staying on top of basic things like cleaning my room etc are equally important.

>$18k federal loans
>2 terms to graduate w/ either math or CS degree, 4 terms for both (which is what I was originally going for)
>$12k savings
>make $60k per year currently at work after taxes
>make $60k per year with business after taxes
>28, upset about not graduated by now, and not interested in my work
I’m glad I got to experience the horrors of beaucracy before applying to grad school, but my ego needs a degree. I was really hurt by not graduating by 28, and only wasn’t able to do so due to some crazy illegal shit inflicted upon me. I had -$8k four months ago, and am up $12k now that I’m not being extorted monthly.

What should I do? I currently work an entry level job, USPS. I could pay off my debt in a few months if I wanted. But I originally wanted to work on stuff I found engaging and interesting.
