Patience in speedrunning

I'm in the midst of Celeste learning/running and idk if I have to capacity to get really good,even though I'd like to get to that level of skill. Even though I'm currently at a skill level where a lot of mistakes are typical,I get very tilted any time I die several times in a row,same with pretty much any speedgame I do,with those several deaths in a row being interpreted by my brain as being incompetent and unable to play the game,demotivating me a ton. This wouldn't do me much good considering it's a given that it takes at least 800 hours to get even just close to good at Celeste,and I'm not too sure if I'm willing to endure that.

I don't have any idea how I'll deal with this tbh. I'll pretty much just play it by ear and see what works. Getting tilted like this prevents me from having fun in speedrunning,at least with tough games like Celeste,and that's a very real problem.
