Learn by your mistakes

For even the smartest player, getting better at the game takes time, energy and commitment. You will lose a lot of games. This is very important to do, as losses are wonderful learning opportunities.

You will not get better as fast as you want to, so relax, don't let yourself get too frustrated with the game. You can't force yourself to improve, but you can study, and the improvement will come on its own.

If you don't/can't understand why a chess game was lost you'll never/almost never improve. JMO.

I've made plenty of mistakes. Hope I've learnt by them.
