There is a Jewish concept called the yetzer hara. Sometimes it is translated as “the evil inclination.” Sometimes it is the thing in your head that tells you that if you can’t do something all the way, don’t do it at all. It is what stops you from doing good deeds and from making positive contributions.
The idea is to catch it in the act of trying to stop you and do something good anyway. It is better to do part of a good deed than nothing at all. Don’t get angry with yourself for not doing the whole thing – at least you did something. However, too many of us think that just doing that little something is enough and so we stop there.
We shouldn’t beat ourselves up for not being able to do all of a good deed, but we also shouldn’t pat ourselves on the back for doing just the minimum. There has to be a balance somewhere. Do what you can, and then try to do a little more.
