@me@h.syafiq-paradisam.my.id learn 1 topic first, commit it with less than 3 years. Once done committing one topic, move on with the new one. Same pattern. If you do a committed learn on it under 3 years, move on with a new one. The only hard and struggle will be preserving those already learned topics while you learning a new one. You wont be a master at one, but at least you will understand things fundamentally. It wont be instant, but you'll have a lot of records when you finally getting older. Having the experience started with software engineering at high school, moved on into music production as side hobby and then focusing on Japanese studies at college taught me that well.
