Lost My Confidence

I wish I never had to loose it. As I said, life is so up and down. Last week, my confidence was above the normal level. I thought, I could do anything as long as I gave all the efforts. But this week, I found out that it wasn't enough. So many external things that I could not avoid to happen. It made me losing the confidence. I am trying to get it back but promised my self that I won't ever let my self elevate it more than its normal level. Only Allah is allowed to do that. I am just a human being. Arrogance doesn't belong to me.
