The fourth one hit really hard because we live in a world where making mistakes has been normalised to an extreme extent, where we stop being aware that we even made a mistake. And I feel that's the case with me (at least that's what my tennis coach tells me, and I kind of see that in the rest of my life)

Fortunately I don't have a problem with not making mistakes, I made a great deal of them (and many more to come) as I have been trying various online ventures for 7 years now (from youtube and freelancing to startups). And in the end some of those ended up working so well I make more than most of my school teachers do per month.

Finally, I wish I knew how not to care about what others think of me. I'm trying to find a way not to worry about it, but I'm still trying to figure it out. I think this will go away with age, as it is with most bad experiences we have in life; the cure to those experiences is to relive them again and again and realise it's not as bad as we make it up in our own heads.
