Short answer: focus on the health fundamentals before anything else.
**Why:** once you have done it once, the second time takes half the effort. Specifically with health: notify your bank before departure.
**Watch out for:** jumping in without a clear goal. This catches a lot of people who assume health is simpler than it actually is.
**To go deeper:** look for case studies rather than tutorials — they show real constraints.
Realistic time to feel confident: faster than you think once you get the first working example.
