Until you learn you've been farming the wrong mob all along. When I was a kid, I was given a "hard problem to solve" by a friend. I tried for years, until a math teacher of mine when I was 18 saw me try to solve it, and just told me "good luck with that, it has been mathematically proved it can't be done".mmmPI wrote: Thu Oct 01, 2020 8:17 am it's the same feeling like grinding for a rare item in MMO except it feel less dumb and repetitive, the hope of sucess keeps me eager to try !
I'd rather know something is impossible, but when it's possible, try as long as needed to succeed
. That's why with hansjoachim's post, once I knew it was possible by just changing my input/output rail spacing, I found my own implementation.
And also that you learned stuff along the way ! practiced things that you'd become familiar with. Maybe the proof of impossibility was someting a 18 Yo person that try to solve math problem for fun could remember, and that would give you confidence and good mark if it was in the math program of an exam later in your studies
