I don't know why but uh....
Sometimes I can be really good at something but there can be time where I can be a total dumbass at it.
Let me make it clearer....
So let's say I do an exercise and I do it really well.
Then the next day, exactly the same topic, similar question. Sometimes my head just decides not to work and I get confused, even when I take a look at my previous work, I can say...
"Huh? How did I do this?"
Then the day after, when I take a look at my exercise again (the one that I didn't do well).
I can do it all of the sudden....
Has anybody experienced this?
