How do the gun guys say it? "I'll quit flyin when you pry my cold dead fingers from around my radio!". 
Seriously bud, as long as you are havin fun with it....keep on keepin on.
Just filled qith cliches, aint I.
I'm not a very good pilot either, but I love being out at the field on a warm summer day, watchin the sun go down in the evening sky.  My club flies at a field in the valley with Lookout Mountain for a backdrop. 
Try to find a way to keep your costs within what you find affordable and enjoy the day.
