I don't learn by being told what to do and what not to do before even doing it. Instead I learn from my mistakes. I learn from the reflection that happens afterwards. I learn by talking to others about it.
Sometimes I learn by having to apologize publicly for my mistakes. There's no better way to learn than having to stand in front of the firing squad and answering to critique.
I learn by doing, by trying new things and by committing to improve on this every day.
