Life is as you see it. This statement was written thousands of years ago. This statement (or a similar version of it such as “life is what you make it, or life is how you perceive it”) is in every religious and ancient spiritual book ever written. It is the secret to happiness.
It is the secret of the ages. What you focus on, where you put your mind, is how you experience life. You choose your emotional state. The external conditions do not make you feel a certain way, unless you allow it. When you control your mind and thoughts, you control your life.
