Ambitious and efficient, you work really hard to obtain your own goals, provide for your family, help your loved ones and friends, impress the world.
But you are also very conscientious, so you know that now it's time you give back with no personal agenda to total strangers.
Pick a cause, event, whatever needs help. Look in your local classifieds (craigslist is a good start, or try volunteermatch.org) for opportunities.
It can be a few hours, one time at a local festival that needs someone to help serve in a beverage tent, or an ongoing youth mentoring program.
Bottom line: you have a lot to offer the world at large. It's time to help out, and the return on investment is priceless!
