Of course it does, the state of mind will affect everything you do, it can even affect your health. I have always been amazed at listening to "famous" people talking about their lives, David Beckham, Geri Halliwell, Madonna, to name buy a few, what amazed me was their enthusiasm/desire to succeed, the lengths they went to to get their goal, their ambition, and sheer determination, nothing just nothing would stand in their way. I find it fascinating, unfortunately I have no determination myself at all, altho I am happy with my lot.
