When to Stop Something

You may see a goal you'd like to attain and think it's something you plunge|plow in and do.  However, if you really didn't do it, you can't pretend you did it.  There are things to consider, like if something is really nice, if it makes sense.  There should be a sign that lets you know if it's probably pretty wrong.  I know, with me, I do some things without thinking, but most of those things aren't the big things.  Also, if I live a certain way, I didn't used to react well if suggestions were made to me that were pretty strong, like not accepting me in a group online because they know I'm not all white.
