Strangely, it seems to me that wanting something too badly seems to have the effect of making the thing you want impossible to get. Have you ever noticed that indifference is the most potent aphrodisiac, that being aloof at a party draws people in your direction?
The other problem is being in a position where it requires the approval of others for you to get what you want. Approval seeking behavior is always counterproductive, demeaning, and leads to low self-esteem.
