My mom always told me that I’m not fast learner, but persistent one. I learnt quite well with my failures, and failures never stops me from progressing. That kind of thing made character on me. And now see myself and try to see what I can do improved.
Grit, the books I read ( Literally listening) before year end; Told me a lot about persistent, skill, expert and master. You always have plenty of room to improve if you looking on. And never doubt yourself on the ability to improving yourself.
