G.K. Chesterton's quotation, "If a thing is worth doing, it is worth doing badly," makes sense when one realizes no one does anything perfectly. How often have you put off doing something because you cannot do it as well as you would like to; as well as you think someone else can do it; or it won't have the full effect you would like it to have?
Whether you think of your family, your local community or the world, this applies. We are continually faced with choices of doing things that will not result in the complete outcomes we'd like. For example-You don't teach your daughter to sew because you don't think you do it well yourself; You have time to do the church posters, but think it won't look professional; You are concerned about starving people in Africa, but do not write to your legislators because you feel you don't know what to say or it won't make any difference.
The one step taken to do something can set in motion a whole series of other, often hidden, things for a fuller, happier life for yourself and others. These are part of the surprises life gives us. But someone who must be able to do something perfectly or nearly so, keeps him/herself from having these surprises.
Perhaps you have heard of the "Butterfly Effect." This refers to the idea that when a butterfly flaps its wings, the energy of that moves a very small bit of air. Yet the addition of that to other air current sources brings about a storm in another part of the world unknown to that butterfly.
So take that chance. Complaining doesn't effect anything except to make all miserable. Try whatever seems important to do in your world. Even if it seems to have no effect on whatever or whomever else is involved, it will have an effect on you. But more often than not, other effects will take place also, even if you are not aware of them.
