That’s the way to go!

that's the way to go

1. That is the best or most suitable decision, option, or method. A: "I think we need to hold a vote with the board members." B: "Yes, that's definitely the way to go." When all of your friends have traditional 9 to 5 jobs with kids and mortgages, it can be easy to feel like that's the way to go, but some people just aren't suited to that lifestyle.
2. A phrase of encouragement or praise for doing something correctly. Now just tighten the reins a bit to keep the horse steady. Yeah, that's the way to go—great job!
