The way to develop self-confidence is to do the thing you fear. The longer we dwell on our misfortunes, the greater is their power to harm us. Learn how to move to a more loving part of your being. It's not necessarily the amount of time you spend at practice that counts, it's what you put into practice. Hatred confuses life, love harmonizes it.
Hatred darkens life, love illuminates it.
If you can imagine it, you can achieve it. If something is wrong, fix it if you can. Worry never fixes anything. They are an opportunity to grow. Half effort does not produce half results, it produces no results.
