Time trouble is blunder time.

My achievements in the field of chess are the result of immense hard work in studying theory.

Drawing general conclusions about your main weaknesses can provide a great stimulus to further growth.

You must not let your opponent know how you feel.

Go through detailed variations in your own time, think in a general way about the position in the opponent's time and you will soon find that you get into time trouble less often, that your games have more content to them, and that their general standard rises.

There is no doubt that the reason for my awful oversight was over-confidence that sapped my sense of danger. So that is where to look for the cause of bad blunders - in the exulting feeling of self-congratulation.

It is better to follow out a plan consistently even if it isn't the best one than to play without a plan at all. The worst thing is to wander about aimlessly.
