It's Easy When You Know How...
This is a saying I say all the time at work when helping people who get stuck trying to do something. I just said it again to a co-worker who had messed up a job even though they did their best. I said," you can't know what you don't know....and there are hundreds, even thousands of little tricks in your bag you only learned from experience. These are things they don't teach in any classroom. Knowing how, comes from experience.
