This, from Christine Kane - Take Action in May, bears repeating just in case you missed it:

Get Committed

When I first began in my songwriting career, I never admitted to anyone that I was a songwriter. I didn’t want them to say, “Oh yea? Prove it!” So, I hedged. I used phrases like “kind of,” “sort of,” “well, not that this could ever happen, but…” Then I found this quote from explorer W.H. Murray –

Until one is committed there is the chance to draw back; always ineffectiveness.

Concerning all acts of initiative (and creation) there is one elementary truth, the ignorance of which kills countless ideas and splendid plans:

That the moment one definitely commits oneself, then providence moves too. All sorts of things occur to help one that would not otherwise have occurred. A whole stream of events issues from the decision, raising in one’s favor all manner of unforeseen incidents and meetings and material assistance which no man would have dreamed would come his way.

I have learned a deep respect for one of Goethe’s couplets:

“Whatever you can do, or dream you can, begin it! Boldness has genius, magic, and power in it.”

I posted this quote on my music room wall. Then, I started to act. I changed my language. I began telling people “I’m a songwriter.” And I started writing everyday no matter what. Slowly, a career grew. And even more important, so did I.
