For me, the worst thing is when something has to do with mathematics. I delegate all my work-related tasks to other people. At the university, I actually asked do my math homework, I found https://edubirdie.com/do-my-math-homework for this. I don’t know how I learned 2 programming languages. This is of course just hard for me.
