I had to give up flying for over 20 years when renting a Chipmunk or C150 went over £6. (The Government stopped giving a fuel rebate for flying.)
I've now been flying regularly for over 27 years, and would have flown more than the 6.5 tach hours so far this month, if the weather had been better.
The important thing is enjoying flying you can afford, rather than looking for some more training for something you'll not use.
