I wrote an article about exactly that a while ago. I called it the WTF factor.I have just started diving, baving only my OW and about 13 dives done. I have my own gear and really like it so far. If anything would cause me to stop eventually it is the grind of driving to yhe divesite, hauling about 40 kilo's on my back, dive for about 30 to 40 minutes and the do it all in reverse (hauling and driving). I would say that, including packing and checking gear, driving to and from, and cleaning and storing my gear, I get about 30 to 40 minutes diving out of about 2,5 to 3 hours preparing/driving/gearing op etc.
In all activities, there is a ratio of Work to Fun. Work is everything that is unpleasant that must be done to participate in the fun of the activity, and that can include just about everything, including the amount of money required to participate. I mentioned above that I gave up skiing. That was partially due to knee replacement, but my orthopedist said I could skill ski, as long as I stayed with the easier slopes. That admonition greatly diminished the fun aspect of it. At the same time, the traffic going into the Colorado mountains on a ski weekend was so heavy that travel to and from the slopes took hours each way. That greatly increased the work aspect, and the WTF ratio was all wrong.
I see this a lot in technical diving. The amount of work and money required for a technical dive is significant. In the beginning, for many people, that extra work is actually part of the fun. After a while, though, the fun aspect subsides, and when it becomes routine, then it is just work. We had a thread maybe 10 years ago about the number of avid tech divers who were dropping out of that kind of diving, and I think that is the reason.
When the WTF factor is out of balance, "WTF" takes on a new meaning, and the participant quits.
