in the future (future) I intended (past tense) to gain a CPL, do some instructing and see what else comes along
If you qualify as a flight instructor you may be able to teach if you have the CPL knowledge, with a CPL you are allowed to earn money.
What do you expect to come along?
For someone who cannot even be bothered to look up the references from readily available sources I would suspect very little to "come along".
I know that some of the youth of today expect to be able to seek instant gratification as a right and I hope that as a PPL you would not fall into this category but FFS!
Surely when you are at the flying club or whatever you can at least speak to a CPL/FI who has obviously already got the knowledge you seek?
Life is tough and getting a licence can be very expensive and quite tough.
Good luck in your quest
