I started flying when I was just a little older than you and found that lessons with gaps in between made it hard to learn. Eventually, for financial and other reasons, I gave it up before getting my PPL. About 10 years later, I went back to it and did my PPL training intensively over a four-week period. It was a much better way to learn and I loved every minute of it!
I don't regret going to uni and getting a job that pays a decent income (it is good to be able to fly and still afford to live! as well as to have a backup career), but I do regret not staying focussed on my objectives when I was younger. It is easy to get distracted by other things when you divert onto another career path for a while, and getting into flying as a career when you are older is much more difficult due to perceptions that accompany age (whether true or not).
