Experience

Kant opening the Critique of Pure Reason

That all our knowledge begins with experience there can be no doubt.
And there is a fair bit of stumbling after that until knowledge and experience are united. For example...
I think that if I had started with the knowledge and experience which I now have I might have made a better garden but it would have been far less rewarding.
