Climb as high as you want. Just don’t use people as the ladder.

Going far is not the problem. The method is where it turns bad. Treating people as steps works for a while and then stops, because the ones you stood on remember, and the world you are climbing into is smaller than it looks. Rising on your own effort and rising at someone else’s expense are different achievements.

Check whether the people who helped you last year are better off for it, and fix any place where the answer is no. Before an opportunity that costs someone else something, ask whether you would explain it to them honestly.
