Its a double edged sword....don't do it and you will live your life kicking yourself and wondering what might have happened etc...
Do it, and (depending on your current level of income, life-comfort, family commitments) you may look at others and think that ultimately you might have been better off in a ground based job which does not necessitate such a large gamble and an even larger financial outlay.
I am a touch over 40, started just flying just after my 30th and now work for a UK regional TP operator. I've had a great time on my personal journey so far - done all sorts - air taxi, skydive work, and now TP. I haven't forked out large amounts on jet TR's (no disrespect to those that have mind,) and still enjoying it (most of the time!!!). Pay is not astounding tho, and yes I could have done better by sticking at the office job I had.
The somewhat clichéd saying "the grass is always greener" applies here. My inclination (especially if you're single) is to do it - BUT huge perseverance and self conviction are needed, and don't expect to be rich for a long time (especially if you end up flying TP's - which is incidentally a great experience!!).
Good luck!!
