Do not become so overwhelmed with the vast depth of the world's suffering and need, and how insufficient you are as one person to do anything about it that you...
a. Desperately try to do everything within your grasp and end up being the superwoman ( or man) on seventeen committees, chairing the PTO, coaching two soccer teams, teaching law full time at the local college, running a marathon, volunteering at the soup kitchen, singing in the choir, maintaining a spotlessly clean house, and cooking gourmet healthy meals three times a day while simultaneously trying to nurture your garden, your partner, your friends, and get four hours of sleep. Believe me, this is no way to contribute or distribute your efforts! It just makes you burned out, cranky, distracted, and exhausted. Plus, there are no brownie points won with God for killing yourself due to overwork and lack of attention to the one sacred body you've been given-your very own.
Curling up into a fetal position with a paper bag over your head saying "it's hopeless, we're all going to die." This is also not helpful to anyone.

C. Any little good that you can do is worth doing.
Which means that just because you cannot solve world hunger doesn't mean that you cannot make some impact in your own community, in some small way. You are also not a bad person for realizing there are only so many hours in a day, and so many ways you can divide your attention. Choose one worthy cause that you are passionate about, pour yourself into it and then, know when to call it a day.
