You entered the dream of piloting at an age when total revenue for a PPL is not to be considered. If you were 20 years older, you could start to think like "spending 10-15k on a license plus annual costs to stay current - is it worth", but, MAN, you are soo young. If you feel you want to fly, GO AND DO. I had a really airyear, closed my company because of the current recession 2.0 and decided to simply go, fly for a year and after that, start to rethink. Nobody will ever be able to pull my memories of these 12 month. It was not so much of airtime, only about 250hs during that year, but I met people and countrysides of Europe I really enjoyed. Flying with the venerable 172 I bought for cheap money and given the fact, that I spent about 150 Euro/hour total costs, up to now and assuming the flying bee is now worth nothing, while still taking me from A to B, I do not regret any penny I spent. I may forget, but the feeling and change remains. Given the fact I am 10+X older, I feel sorry, if you don't feel your youth!
