The primary cause of unhappiness is never the situation but your thoughts about it. Be aware of the thoughts you are thinking. Separate them from the situation, which is always neutral, which always is as it is.
You are the most constant thing in your own life. Befriend yourself first. Invest in yourself first. Become yourself first. The rest will come together in time.
โIf your mind carries a heavy burden of past, you will experience more of the same. The past perpetuates itself through lack of presence." - Eckhart Tolle
