Yeah, defo agree with this. A lot of this is just good life advice for anyone at this stage in their life, but it also is particularly true when you're in the US because:

* Cooking for yourself can be vastly cheaper since there will be steep discounts on food that is about to hit its sell-by date: this food is still usually good for a couple of days. This isn't something you see in every country.

* Gym facilities are really good even in US unis that are only top 50. Like exceptionally good. Squat racks, benches, lots of weights, indoor tracks, sports courts, cheap or free rental equipment. Uni healthcare is also pretty decent unlike general US healthcare.

* The US definitely has a binge drinking problem that is worse than any other country. Participating in many social events will require partaking but if you're smart you can ration the alcohol and still get almost all the social benefit. You definitely don't want to attempt to keep up with the Americans. They are very friendly and will offer you lots but if you've always got a non-empty cup you'll be okay
