Help me find the exact platitude.. Something like "You can only discover the path through work"..

It's a saying/platitude that you would say to someone who is stuck in idea/fantasy mode.

What's the saying -- I can't think of it but it's something like "Let the work lead you" or "You'll only discover it through work"... i'm sure there are multiple versions. Post your favorite one here!

You can only get there through blood, sweat, and tears?
