more power to (someone or something)
May someone or something find success in their activity or pursuit. Hey, if they want to spend all their free time in front of a computer screen, then more power to them. You want to be an auto mechanic when you graduate? Well, I don't have any idea what I want to be, so more power to you!
More power to you!
Well done!; You really stood up for yourself!; You really did something for your own benefit! (The stress is on to, and the you is usually "ya.") Bill: I finally told her off, but good. Bob: More power to you! Sue: I spent years getting ready for that job, and I finally got it. Mary: More power to you!
