Thinking too much?

I plan just about everything... I have to know what I'm doing at all times.
This includes much of what I say. When faced with a situation... I am very quick to think... and over think... everything I should and shouldn't say. I am so afraid that I am going to say something wrong and I will hurt someone, or that I'll hurt myself, after all who wants to make themselves look bad?! I will say though, I can't even tell you how many times this has back fired on me... and I end up doing what I hoped I wouldn't... saying something wrong.
I would love to be able to speak my mind... to say what's on my heart. I don't know why that has to be so hard for me. Fear... that sums it up pretty well.

God used my devotion time, again, to get me thinking.

But when they deliver you up, do not be anxious about how or what you are to speak; for what you are to say will be given you in that very hour and moment, for it is not you who are speaking, but the Spirit of you Father speaking through you. Matthew 10:19-20

"Do you realize how much peace can be ours if we will just stop trying to figure out in advance everything we need to day and do in every situation we face in life? If you are like me, you wear yourself out trying to prepare yourself for every situation you are likely to run into in the future. You try to plan and rehearse every word you are going to speak in every interview and conversation. Jesus is telling us here that we don't have to do that. He is telling us to trust all that to the Holy Spirit who will guide us and direct us.
When we do have to make hard decisions or solve complicated problems or confront difficult people, the Holy Spirit will decide the proper time and the best approach. He will give us the right words to say. Until then, we don't need to bother ourselves with it. If we listen to what the Lord is telling us here in this passage, not only will we have more peace, but we will also enjoy more success. Because when we do have to speak, what comes out of our mouth will be spiritual wisdom from God and not something that we have come up with out of our own carnal mind."
-Joyce Meyer, from New Day New You

Reading this was like looking in a mirror. I realized that I am putting so much pressure on myself for nothing! The fact is... I don't have to have things figured out. Wearing myself out about what I should or shouldn't say shows that I'm not relying on the Holy Spirit's guidance. Wow! that's big. This, once again shows my lack of trust. Ouch, I feel that in my heart! God is amazing in the way that He lovingly and patiently molds us to what He has called us to be.
