For me airsoft is like going on holiday. Yes it can severely dent the bank balance, yes it's can be an arse ache to get all your stuff sorted (although now I just stick some music on, have a beer and do it at a leisurely pace a good few days before). Then you need to get up early and load the car etc. However most of the time I enjoy the destination, so feel it's worth pushing through all the other crap.
I can then play a half-day and be home for lunch, already feeling like I've done something with my day. Whereas otherwise I'd still be scratching my arse on the sofa.
