Well you could do the PPL first and see whether you like flying.
Then enroll on the ATPL course.This will take 6 mths if done full time and between 12 to 18 mths if Distance learning.Have the odd hour flying here and there to keep your sanity.
Then with the exams out the way,structure your hours building towards the CPL.
Take an Instructor up every 10 hrs or so,and don`t just fly round in circles.
Once hours are built you should be up to speed and ready for the CPL.
