I know that's how the saying goes, but I don't think I would be saying now that I'd wish I had gone traveling if I had not done it. I'm pretty such I would not be wishing for traveling if I'm at the same state of happiness as I am now, and I could have reached the same level of happiness in life if I did not travel (possibly even earlier).
Traveling objectively made me worse off than if I had not done it.
