And it is certain that you can do what you want to do; the desire to do it is proof that you have within you the power which can do it.
Desire is a manifestation of power.
The desire to play music is the power which can play music seeking expression and development; the desire to invent mechanical devices is the mechanical talent seeking expression and development.
Where there is no power, either developed or undeveloped, to do a thing, there is never any desire to do that thing; and where there is strong desire to do a thing, it is certain proof that the power to do it is strong, and only requires to be developed and applied in the Right Way.
