Because a thing is difficult for you, do not therefore suppose it beyond mortal power. On the contrary, if anything is possible and proper for a man to do, assume that it must fall within your own capacity. - Marcus Aurelius
Whatever your target, goal, or vision — begin first with belief.
Then rub your vision up against reality. Expect obstacles. Find allies.
But whatever you do, and however it goes, begin first by believing in yourself.
Assume that it must fall within your own capacity.
Assume you can.
