i think therefore i’m not?

Why do I feel the need to put “I think” in front of everything I say? 

It might be a confidence thing. I THINK “thinking” is more temporary than feeling or wanting. If I put the term “i think” in front of the sentence, I am safer. All it takes for me to change my mind, is a second. 

Feeling and wanting are such intense emotions that it doesn’t deserve to be treated so casually. When I feel or want something, it’s beyond thinking. It’s the difference between surface level and deep down. 

Adding the “i think” changes it from 100% purity to a solid 85%

Do I care if it’s an unstable mindset? Is it hurting me?
