Do you say "You've got the upper hand over yourself much more than you do over the world" or "You've got the upper hand over yourself much more than you did over the world"? Or "You've got the upper hand over yourself much more than did you over the world"?

When you have the upper hand, it is always over someone or something else. For example: When is comes to dating women, rich men always have the upper hand." or: "Modern cars have the upper hand over antiques on gas mileage."

If you want to compare yourself to the world, you might say, "What it comes down to it, the world always has the upper hand."

"Comes down to it" and "upper hand" are both idiomatic phrases.

"Comes down to it" simply means "the final conclusion" and "upper hand" may be from chilren's playgrounds. Someone would toss a bat to another child, who would catch it (in a vertical position, with the handle end up) somewhere along the length. Then, the children would take turns putting their hands above the previous hand. Eventually, someone's hand would hold the very top. That child would have the upper hand, and get to be first.

And yes, I used to do this as a child. :-)  If you have any questions, let  me know.

"You have the upper hand over yourself much more than you do over the world"

Why would you have the upper hand over yourself?
