Always be who you want to be, because as long as you really want to be someone you become such person and the perception of your position is only perception of yours.
The true acceptance of your self is quite easy as soon as you realize, that in fact you want to be only a bit different from your starting personality or state. Eg. many people want to be a milionaire, but very few succeed. There exists a positive correlation between idea, hard work, education and abilities AND being a rich person, believe me. My point is that you can't really tell that you want to be a milionaire sitting in front of your TV(without idea,plan and EFFORT), because, obviously, realizing a necessity of change is crucial, but action plays fundamental role in changing oneself. What I wanted to say is that you really don't want to be a milionaire, you just dream of being one, but you want to be a bit richer. And all you do is being more efficient at work, spending less, giving up addictions etc. So, in fact, most of us have problem with undertaking proper action to their desire and distinguishing between what we dream of and what we pursue.
Another issue is that being rich is relative. And maybe thats wrong example above, but I hope you got my point.
