I'm one for enthusiasms, like toad of toad hall. I got a computer and broad band and all the kit and told everyone about it, then it was window cleaning. I got one of the early mountain bikes cannondale full sus in the nineties 2k, the problem with that was everytime i went out it drew a crowd.
Other enthusiasms have been making a lot of money, hot systems, electric reel, and currently i'm obsessed with gutters.
Bookeeping too, and software to do it. I would have been a good accountant.
Holidays is a fairly new one, dom rep, cuba, egypt, turkey...... But I often spend my time away plotting how to make money.
