jonny, follow your heart mate , im 36 and have had a PPL for 6 years. I have just finished the ATPL's and start the CPL/IR on Monday already having 213 hours.
I was always on with the groundschool but time , job etc always got in the way when suddenly my sis in law dies of cancer at age 33 ,my personal kick up the harris.
I know that if i do this and dont get a job then i tried and i wont wake up at 50 and think what if ! A friend of mine got his first job at age 39 , almost 40 with TUI on the 737 , hes now on the TR for the A320 with Qatar 4 or so years later.
Each to their own i say and every situation is different, find a local flying club , theres generally a wealth of knowledge there and many people in many different situations.
Good Luck whatever you decide to do
