The road to happiness lies in two simple principles

"The road to happiness lies in two simple principles: find
what interests you and that you can do well, and put your
whole soul into it -- every bit of energy and ambition and
natural ability you have."

-- John D. Rockefeller III

Choose what you want then put your time, effort, and focus into it.
Reaching ambition is possible if you learn to utilize your available tools.

It is impossible for you to gain your happiness?
