I'll "just" do it myself

I’ll “just” do it myself.I’ll “just” pay someone else do it. All of us have uttered those phrases, unaware of the horror that awaits. It’s easy to think we can solve a problem quickly and easily if we “just” do it ourselves. Or cheaply, if we “just” pay someone else to do it. When you don’t know what you don’t know, things can go comedically wrong at speed. Something you thought would be quick, easy, and cheap, turns out to be NONE OF THOSE THINGS. What can we do about it?
