My plan how to learn math: Since I had to fill many gaps, I bought some school books to solve basic problems and first get a better math intuition. Since problem-solving is the key to gain a good understanding and intuition I started with that. I also used Khan Academy where I revised fundamentals as well. In parallel, I wanted to start all over with proving, and therefore I started working through How to Prove it.

Why am I learning math in my free time? During my time in school, I used to be a pretty bad student and was often referred to as the clown. I made everyone laugh and my teachers cry. In this time I never really learned or put in some work. I asked classmates for homework, tried to pass exams which resulted in bad grades and so on. My math grades were pretty bad as well, what a surprise but I was still somehow fascinated by the nature of math, which was the reason why I took the so called “Leistungskurs” in German schools.
