I earn $2k per month.. my ex-husband left me and my daughter for another woman. I don't have a degree because a single mum like me (working full-time) does not have the money, time or freedom to attend night classes. I dream of financial independence everyday; but in reality, my salary is barely enough to last me until the next payday.

To Mr Twentysix, you can consider saving up to buy freehold properties and accumulate more wealth from your investments... hmm... but then at the end of the day I think having even having billions won't make you happy if you do not have loved ones (family members) beside you to share your life with...
When you are extremely wealthy, you can essentially get any car/house/woman/anything that you want... but there is also a possibility that family/friends/women starts seeing you as an ATM machine rather than a living person with emotions.
Poverty can cause depression, so can wealth. Seek help if you find your life meaningless and no longer worth living... =)
