Make it out, then come back with something useful: a scholarship, a workshop, a phone number that opens doors.

Leaving a hard place is one thing, and lowering the wall behind you is another. What actually helps the people still there is specific and unromantic: money, instruction, access to someone who picks up the phone. Encouragement on its own is cheap and mostly ineffective, because the barrier was never a shortage of belief.

When you have something to give, make it concrete. One introduction, one paid opportunity, one hour of teaching a thing you know. You do not have to wait until you are established, since the person two years behind needs what you learned last year.
