I can feel guilty about the past, apprehensive about the future, but only in the present can I act. The ability to be in the present moment is a major component of mental wellness.
Abraham H. Maslow
I believe that everything happens for a reason. People change so that you can learn to let go, things go wrong so that you appreciate them when they're right, you believe lies so you eventually learn to trust no one but yourself, and sometimes good things fall apart so better things can fall together.
