Chrome, you remind me of me. We can see how to get to where we want to be at the intellectual level but lack the proper conviction and follow through to make it stick. If it is any consolation, people like us tend to be far more critical and introspective regarding our "failings" than the significant others around us tend to notice. We tend to be our own worst critics.
I don't have any great advice. I don't have any great track record either. I do know that if we try to follow what we know will work we need to believe in it. Hell, I have faked it and it helped. I can only imagine how much it would help if I believed it deep down and was able to tailor my actions accordingly.
Gone the carvings and those who left their mark. Gone the kings and queens, now only the rats hold sway.
