Lean not on your own understanding

I have been talking with God about the verse that says "lean not on your own understanding". And I got a revelation. Now It seems really simple, but it just clicked with me, so bear with me. I have been leaning on this verse a lot lately because a lot of things have been going on that I just don't understand, and I want to understand, and I get depressed and frustrated when I can't, so I have been leaning on this verse to give me peace, and to turn my focus back onto trusting God in everything. But I was talking to him today, and I focused in on "YOUR OWN UNDERSTANDING" and God pointed out to me, that this also meant that when I think I DO understand, that I am not to lean on it either!!! Wow, that made me think, I tend to want to control things, and I really want to figure things out, but even when i do understand, (or think that I do) I am to completely surrender that too!! Because, I need to surrender my expectations. God talks to me constantly, and he is always revealing things to me, BUT I am human and even though His word has never been wrong, my expectations of that word, can be off :) And when my expectations get thrown to the wind, I get hurt and angry. So I am learning to continue to have faith, continue to hear God, continue to have understanding, but to not lean on what I think I understand! To submit it back to God, and then when it comes about, I am excited and not disappointed. (or at least this is the goal:)
