Sir Winston Churchill used to point out that one vital ingredient for eventual success was the ability to go from failure to failure without loss of enthusiasm.
... in other words, fall flat on your face, pick yourself up, and keep going.
I am personally convinced that people nowadays have forgotten this... if they ever knew it.
This I already know. Not enough people know that, and it can feel incredibly frustrating seeing people pointlessly hopeless. In regards to its application in chess, I'd prefer to apply that mindset to something more important or fulfilling than chess. Some people need chess for the reason you placed or at least be one useful source for that mindset to grow. It doesn't make chess bad but it also doesn't make it a perfect fit for everyone, just as DnD or Dark Souls aren't a perfect fit for everyone.
It's totally okay to take a break and think about what you really want to spend your time on. If chess isn't making you happy and just feels like a headache, there are probably other things you'd enjoy more. Feeling good mentally can come from lots of different activities, so try to find what makes you genuinely happy and satisfied. It's all about picking things that make you feel good and bring some extra positivity into your life.
Exactly! Thank you!
