Hi Jjoe,
It seems that after getting over the excitment of obtaining your license, you are looking for more challenges, you say that flights from A to B will become boring.
I am suprised that no one on here has yet mentioned instrument flying. Get some instrument time in with an instructor and this will improve your ability to stay safe, even if you do not yet wish to go for the IR(r) qualification.
Best Wishes and congrats,
Meldrew.
