If you learn to use the tools of body, mind, emotions, and energy by choice, you will naturally become a very impactful human being.  

If your happiness depends upon what is happening outside of you, you will always be a slave to the external situation.

The more you become conscious of your actions, the more you gain control over what happens within you and, to a large extent, around you.

If you want to get involved but not entangled, volunteering is a powerful tool. You should make use of it, to make activity a tool for your liberation.

Engineering the outside world can create comfort and convenience. Only engineering your interiority can create wellbeing.
