If you are middle class (~$30k-$70k per annum) you can be wealthy* by focusing your spending on freedom, aka capital investments. I did not understand this was an option before reading the blog of Mr. Money Mustache[0]. Reading that and the Living a FI blog[1] may hopefully be as life-changing to you reading this comment as it was for me.
* Wealthy in time to spend with those you love
