One of the 5 ways to increase your grit is practice, practice, practice. By this, Angela Lee Duckworth means to practice deliberately. For example, let’s say you’re a musician. It might be tempting to play that piece that you know so well, the one everyone compliments you on. But you’re not going to get better by doing that. You need to practice that four octave scale you haven’t nailed yet. You need to go slowly, hit each not just right and start over when you get it wrong. Boring! Tedious! But so critical.
This is grit.
It’s hard and it’s boring and you need to do it every single day. You need to be consistent.
That is how you get better.
By the way, you can substitute anything for practicing violin: football, soccer, dance, writing, drawing, painting. If it’s worth doing, it’s worth doing extremely well.
