I remember creating a "Sickness system" when I was 15 years old
It allowed me to progress in my studies and my decent youtube channel (which I left xd)
The reason why I did it, is that I have a tendency to fall sick very easily, despite how hard I try to improve my immunity and surroundings.
"rest and wait", was very useless for me
I had to play the cards I was dealt right.
I shared my system in the comments, how about you?
