It's that way with starting a business or a charity, as well.
Don't save Bitcoin up, for years and years, to start some endeavour, some day. It'll never happen. Hit the ground running, right this second. Just do it. Scrounge up the money, as you go along, or figure out how to get it started with no money.
Time+effort is more valuable than money. Money is only stored up time+effort, but efforts are always most-effective at _some particular time_.
You are having the idea for your endeavour at this particular time because the time for your endeavour is now.
