Instead of this.... Say this instead!
I'm not good at this. I need to keep practicing.
I'm awesome at this. I'm on the right track.
I'm stupid. I can get smarter by trying hard.
I give up. I'll try another way.
I quit. What will I lose by trying?
This is too hard. This will take some effort.
This is too much. This will take some time.
I made a mistake. Mistakes help me to learn better.
The first try didn't work. Good thing I can try again!
I can't make this any better. I can always improve my work.
It's good enough. Is it really my best work?
