If you have experience and can reapply knowledge, you’re going to devise and follow a process/procedure based on your experience. OR you’re going to find someone with more relevant experience and get their help crafting the process/procedure.
If you’re not following a procedure you’re making shit up.
Making shit up is what you do when you’re dumb and can’t reapply knowledge.
We’ve all been there. We’ve all done that.
BUT we can win, when we realize we’re making shit up.
