To me, there's no point in saving more if you still have other bills and stuff to pay. Now if you was living your live debt-free, then I can see you saving more than that. But if you still got bills and stuff, get a nest egg up and take care of that 1st. Then you can afford to eat and live a little better but still saving at the same time.

but once you do
save for a rainy day fund
and then invest your money
get a CD with a decent interest and get a loan off it to increase your credit score
