It seems to me that a lot of people are suffering from not being able to arrange to fly when they want to, due to
1 - weather
2 - personal availability
3 - aircraft availability
My suggestion is to look at what can be done about these.
1 you can partly fix by getting an instrument qualification. It is also the case (a slight paradox, this) that to fly to the limits of legal VFR you jolly well need a full instrument navigation capability. I have an IR and would cancel perhaps 25% of randomly planned future flights. If I had only a plain PPL I would be cancelling at least 75% of randomly planned flights. But the % figures also depend on whether the plane is half decent - a piece of junk is no good even if you do have an IR (or an IMCR). They also depend on the availability of instrument runways.
2 and 3 are personal things. If you buy a plane of your own, or buy a share in a well managed small group, then you get good availability. You also get the lowest marginal flying costs.
