What you will do is acquire a hobby that has the potential to motivate you to learn a *LOT* of mathematics, much about the how the internet works, software development, and most of all patience (possibly the most important skill for any investor). At some point you'll even learn a bit of electronics, at the very least the relationship between volts, amps, and watts (and what the latter cost).
Meanwhile, think of investing as developing strength (or losing weight). You don't test everyday; you develop a plan and stick to it. Then at intervals you test (your plan) and make any changes you need.
Good luck!
Hobbyist mining seems appealing to me. What kind of math is bitcoin?
Bitcoin (and all cryptocurrency) is based in cryptography. There are tons of articles available online that explain things fairly simply, e.g. this one on Investopedia: https://www.investopedia.com/tech/explaining-crypto-cryptocurrency/
Obviously you don't have to understand it to mine successfully, but it is something more or less useful to know and gaining some mastery of the field could lead to opportunities in the software side of the industry.
