All of the posts here are about giving up good jobs to follow the photography path. What about if you started over again and had these thoughts when you were in your 20s say?
I am 27, have a boring (I mean REALLY boring) job that is often 13 hours a day. Sometime a lot of work other times I can be lucky to pull in £100 a month (yeah I am serious!). As a result I am still having to live with parents. Give that kind of a situation surely the choice is easier to follow a love for photography. I mean it's not like there is much to lose financially.
As you say,you got nutin to lose,go for it,better to get low paid for somthing you love,than somthing you hate
