I am all around,
You see me all the time.
Almost everyone has one of me;
Those who don't, need to get one of me.
Most can spend me on almost anything,
but if you spend me the wrong way you may regret it,
For I can only be spent once.
Who or What am I?

I think more or less precedent answers fits with the riddle but they are not totally convincent, while probably "life" could be a solution. I should add another not convincent answer:

happiness
