Growing up my parents never told me off if I got a poor score on a test. It didn’t matter to them if I wasn’t as good at Physics as I was at English, as long as I continued to try my best.
But I was told off for things that required zero talent. Leaving a textbook at home or missing the school bus would have meant serious trouble, because 99% of the time they’re inexcusable mistakes.
In life there will always be times when you question your talent, whether your self-criticism is justified or not. Those challenging moments are easier to work through when you’re already practicing a few positive things that require zero talent each day of your life.
