Don't get mortgages/private schools/expensive cars or hobbies that you can't manage comfortably with 2/3 of your income (or if in faang-level than 1/3 to 1/2 max).

Even less if you need to pay for your own healthcare outside of working contract.

I know its very luring, but its a one way trap into misery and ruined life one way or another. Doesn't matter how well current economy is doing, what are projections etc. thats a basic 101 mathematics.

Well you need to live someplace and homes near the best jobs are the most expensive, all new cars and many used ones are expensive, and state universities can also be expensive these days.
