Sometimes we are harder on ourselves than on others. For example, if someone does a better job than we in performing a certain task, we can accept that because the other person is better. But if our performance by ourselves falls short of our own expectation or goal, we get really disappointed. The Lord showed me that I shouldn't distinguish between the two. In either case, pride is involved. As long as we do God's will or at least have good intentions, we should be content and let neither success nor failure affect us.
