Do it now RC! I started in late April and finished 11 months later, with one longish layoff around Jan-Feb and a couple of shorter ones along the way. One problem with putting things off is that you can't tell what turns your life might take. I meant to get a PPL when I was in my mid 20s, but didn't; planned it again again just after turning 30; but did nothing, and finally knuckled down and got it in my late 30s on the basis that otherwise I'd have kids and would never do the thing.
