We Are the Makers
Happiness is not something ready made. It comes from your own actions.
-- Tenzin Gyatso, the 14th Dalai Lama
If you are religious or spiritual, and you believe in a higher power, then do not confuse being a believer with being powerless. Not only is happiness something we have the power to create, but experience has proven that happiness is something only we have the power to create. Do not pray to be given happiness -- that's not how happiness works.
If you are often unhappy, then perhaps you are caught in the trap of waiting. Do not wait for better circumstances or for an achievement in life before you allow yourself to feel happy. Being happy will not stop you from working hard toward your goals. To the contrary, a positive attitude is proven to increase productivity. Motivation and productivity do not require suffering. This is your one life. Be happy now, while still working toward your goals.
Most importantly, being happy can only come from within you. External circumstances such as more material success do not give you more happiness. Many of the most powerful and wealthy people are also famously unhappy. Happiness is something you choose -- it may be inspired by others or by your circumstances but it does not depend on them -- being happy depends on you.
