The only way IMHO, is to BUY BUY BUY. If you rely on renting then of course you gradually fade away as it becomes too much hassle. When you own, or own a share, you can use your plane like you would a car pretty much - i.e. when you want, for as long as you want, and no one is going to run up to you and give you a bollocking for walking across the apron with a baseball hat on, or give you a bollocking if you arrive back 1 few minutes late - or don't fly...etc.....
