Very little -- that's the point. When you're in a position like this, you're not thinking long-term because 1) the short-term requires your immediate attention, and 2) even if you come up with long-term plans, it's going to be very difficult to execute them without money.

This is by no means a value judgement -- been there, done that -- and more just a reality of the situation.

Actually you can do all the long term thinking you like, you'll just be unlikely to be able to implement any of it since you won't have the money.
