Earlier quoted context omitted.
I still said that when I had a negative checking account balance while starting my company. I think you should worry about money, but that you should take a long-term view of it.
Only people with a nice fallback cushion can afford to say "take a long-term view of money" when their checking account is in the negatives. Let's face it: if you are having trouble feeding yourself, your view on money will be extremely short-term. As it should be.
So the difference the extra money makes is likely to just mean lifestyle changes like taking the bus instead of driving a new car and less ambitious holidays. If you can put up with that for a few years then it makes sense to take a lower paying job if you believe it will have better long term prospects.
