I am 31 and trying to land a lifelong career.

So far in 10 years since school I've changed over 10 jobs in different fields, and tried to run a home business unsuccessfully as it made $0 money.

Typically, I would start a new job in the spring, then by winter I'd get sick alot and depressed. (I live in the nyc area so winters are brutal). and I'd lose focus and interest and end up quitting by march/april usually. I do have a focusing problem I noticed I daydream alot at work.

Now I have a spotty work history and lack some solid work references. This keeps coming up in interviews and background checks and I am not getting hired.

Any advice to save me from the welfare line and the street?
