I did the same thing. I was in a good corporate job (non aviation), late 30s and making good money, although already married and have kids, and I gave it all up to pursue my lifelong dream. Looking back, aside from the lack of income, it has been great. There truely is no other job like it. I am able to hold another day job to supplement the funds. (I know thats another story, no pilot should HAVE to have a second job). But i already had the big house and lifestyle to support. When/if i ever make it to Capt, then I will have some breathing room. But overall, if it is your "dream" and not just something you'd like to try, then do it. You will make it work. The above poster was right, its usually the pilots who have not had another career that complain the most.
