If you're God's workmanship (and, indeed, you are - Ephesians 2:10), then your part isn't to work but to relax and know Him and how He is with you. Jesus is your focus because you’re His. He'll take care of the building and the result, because He knows what He's doing. You don't have to. He’s the Expert. That’s why you feel better after looking at Him or talking with Him.
You look, He works.
