The most marvelous thing about the mind is that it has no limits. Remember "Princess Caraboo" (if you haven't seen this movie, you probably should)? Her mental ability was two-fold: to invent a personality and history that would attain attention, and to brazen her way through seemingly insurmountable odds. Both of these skills are attained within the mind.

The thing about training the mind is not in exercise, but rather in the very conception of an idea in the first place. It is your own definitions, your own perceptions, which give an idea its limitations. If you do not percieve any imperfections, then it has none until you do. Doubt, greed, lust, happiness, courage, all appear in your life as you need them, in whatever form you concieve them to be, and with whatever limitations or powers, or even behavioral characteristics.

Now, when you wish your mind or personality to assume a form, concieve it in your mind's eye as what you wish it to be, and then trust that conception's completeness. Follow its commands, believe its visions, and trust it in the way you would your dearest companion, your most powerful ally. In this way, your vision becomes as real as the value of the trust you place in it.

Reinvent yourself at need.
