Why Don't I Trust Myself?

This isn't really apropos of anything going on in my life right now, but the other day, I realized that I really need to start trusting myself, specifically my own instincts more. For some reason, I was thinking about times when I've gone against my instincts and allowed myself to be convinced of things - whether it was believing a certain thing, or taking an action. It was usually friends trying to boost my self-esteem or get me to take a risk. This isn't about blaming my friends. They're a loving, well-meaning lot, nor am I feeling like blaming myself. Blame's a bad word here (Trust me, I can justifiably blame myself for plenty of other shit).

The message from my instincts is always the same "This doesn't feel right!" So why don't I listen to them? They're right 99.99% of the time, but I don't trust them. Seems illogical (Egads! now I am quoting Mr. Spock). I never trust myself to heed them. I always assume other people know what's best for me. no one knows me better than I do - except my Creator. It's time to start trusting myself.
