Generally, very true in mental health, but moderately true for all areas of health: The idea “at least we have systems/doctors/drugs to help solve this if/when it becomes a problem” is a massive cognitohazard. You do not want to be on the other side of that fence, and belief in solutions there will slide you toward it quicker. Do everything you can to avoid it while you’re on the other side.

e.g. if you aren’t getting 10,000 steps every day for six months straight, you aren’t doing everything you can. It might not solve your problems, but you don’t know that, because you’ve never tried. If you aren’t quitting nicotine & alcohol, you aren’t doing everything you can. If you aren’t saying hi and being shot down by at least one stranger you find attractive every week, you aren’t doing everything you can.
