Doing better than your parents isn’t betrayal. For a lot of parents, that was the whole point.

Outpacing the people who raised you can feel disloyal, as though doing well were a comment on them. Usually it is the reverse: the work they did was aimed at exactly this, and your progress is the thing they were buying with it. Guilt about outgrowing a situation is common and mostly misplaced. Taking the opportunity honours the effort more than refusing it ever could.

If you feel that guilt, say something about it directly. Thank whoever raised you for one specific thing they made possible rather than in general terms. Most parents want the news said out loud.
