Yes, on your way you need to clear your goals in your head... you want to be a hobby pilot, flying from A to B, for fun, or you want to do this for earning money?
As a Private Pilot, you can take passengers but do only cost share, not earning from it. During a CPL course you learn the aspects of commercial flying and taking responsibility as a "professional" pilot.
But if you love flying - you will see in your ppl course, after some experience you can think of becoming a pro, but starting with ATPL theory, not CPL.
