Surprising fact
About 80% of personal trainers quit within 2 years because the math doesn't work at big commercial gyms ($25/session × 20 sessions/week = $26k/year). The 20% who survive usually go independent, build a book of 15-25 regular clients at $100+/session, and clear $100k+.

The real cost will be different for you
The numbers above are medians from the U.S. Bureau of Labor Statistics. The price you actually pay depends on financial aid, scholarships, family help, state residency, and which schools accept you. A "$250k" private university is often $60k to $120k after aid. A "cheap" community college can still be out of reach without a plan. Use these as a starting point, then get real quotes from the specific schools you're considering.

Read, listen, watch
The cheapest way to find out whether you actually like a field is to read what people in it read.
'Being Mortal' by Atul Gawande (what medicine gets wrong about the end of life)
'When Breath Becomes Air' by Paul Kalanithi (a neurosurgeon's memoir)
The NEJM 'Case Records' podcast (real diagnostic mysteries, free)
Medscape and STAT News (daily medicine journalism)
None of this is required. It's just the lowest-friction way to find out if you actually like this kind of work before you commit money or time.
