from an 11-18HOD/ppl
I did mine by booking a lesson a week (on Sundays - I use Saturdays to rest up). Some weeks the weather stopped me, but not too many, since I was prepared to fly for the experience, and not just for the curriculum.
I took 5 months to solo, 2 years to licence. Up to ppl status, I enjoyed the flying as much as any I've done since, especially the nav challenges with an instructor adding to the challenge (by tossing in distractions etc.) if it was getting too easy...
Cost to ppl was never an issue for me. The cost of flying was all that mattered; the ppl arrived when it was ready. The licence is nice to have - it allows me to take other friends as well now, but mostly they are less fun than the instructors.
If you are below retirement age, it should on the law of averages take you less time than it took me.
Go for it.
