While I applaud Australia's initiatives, I am becoming more and more convinced that a lot of people are already in (or heading towards) situations that the mental healthcare field can do very little, if anything, to improve.
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.
