Re: Things I want to learn how to do
I would like to "train" a Bonsai tree. No real reason why, just find it cool.
I would second the notion of being able to do basic automotive work. The guys I work with do all their own car maintenance and just about all I'm confident doing is changing wiper blades.
One other... I'm not a drinker, but I'm mildly fascinated by people who make their own beer and wine. I'm almost tempted to do it, even though I really won't take advantage of my own product.
When all is said and done more is said than done.
