The purpose of psychology is to understand how we cope with the world.

Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.

The mind is a dynamic system that constantly adapts to its environment.
