Find me and take my hand in marriage. NOW.

Can anybody think of a word/term that describes the following:

Let's say there's one thing that you're very good at and another thing that you're very bad at. When you work at becoming better with the thing you're bad at, the thing you're good at begins to suffer.

There has to be a word that fits this and I can't think of what it may be.

Also, I heard some sports talk show host refer to a recent guest they had who was a golf writer and analyst. He said that this expert had a theory in which golfers with a specific flaw in their game would compensate for that flaw and consequently would develop OTHER flaws as a result of those compensations. This seems like something that's not just exclusive to golf but encompasses life as well. Does anyone have a word for this?

Any suggestions?
