Begin it

In one of my school presentations in Singapore, I was shown a mural that the final year students had made as a parting gift to the school. The ideas execution part of me just loves the message they left for the upcoming students:

Whatever you can do,
or dream you can,
begin it. 

So, don't wait for opportunities to knock on your door, and don't set up parameters to delay your dreams.
Begin the quest, today!
(And if you want a hand, my goal getting video could be a helpful place to start).
