Your first priority should be taking care of yourself. Remember the plane safety demonstration? You always put your own mask on first, even if it seems selfish.

You're in the best position to help others and make good decisions when you feel stability in your own life. Making sure you'll be around a long time also makes you last longer as a resource to society, and to your family.

You can't do any of those things you mentioned if you're dead, sick, or miserable.
