Resilience: The Art of Bouncing Back
Build up your ability to be resilient, your ability to bounce back after a fall. As it states in Mishlei (24:25), "A righteous person will fall seven times and rise up." Everyone can fall; the main thing is to get up again.
When you think in terms of building your self-image, you will focus on the fact that you rose up after you fell. Of course, it would be best never to fall at all. But since falling is part of life, build your self-image by keeping your focus on what you are doing right. And when you fall, keep your focus on what you need to do to bounce back.
