Edit: Most of my work is my hobby as well; coding, starting companies, convincing great people, working with great people. When all is running smooth it's like a hobby. And for a while the hard times are fun as well to get sharp again.
Guess it's waiting for Glass or something to hurry the .... up. But that'll probably be disappointing as well; seems we are quite far removed from this. So for now I'm focusing on the software side, like having a live/reactive, predictive programming language which can be used almost only with alphanum chars. I have a lispy (but it would work with all lisps which don't have syntactic sugar) which predicts the parentheses well enough to almost never having to type them. This helps with entering code faster with one handed keyboards and voice (which I think is a dead end btw). However the issue which always arises is editing code, not adding code. That is also something you can reason about and try to solve without having the actual hardware, so it's something i'm working on. When I have time (i'm in a startup, unrelated to this hobby right now), I will blog about everything. I promised myself this will be before the end of the year ;)
I also enjoy riding my motorcycle, reading literature, weightlifting, photography, and playing Battlefield 2.
I am learning to play piano and chess.
This should help you on your way:
If there are any golf courses around you, check their clubhouses for a local pro. There's usually someone around giving lessons.
This is where you need to spend the most money. Buy 5 or 10 lessons. Learn the fundamentals first, dont worry about distance, worry about contact.
Do this instead of a "craigslist deal". You'll be sure to get sound advice from someone who really understands the game.
For clubs, buy used or secondhand. These will last you until you either fall in love with the game or give it up and something else.

They're usually pretty low-cost and only 9 holes. As someone who enjoys playing golf, but doesn't have it as a top priority to get better at, 18 holes of a real course can be exhausting and frustrating if I'm not playing well. 9 holes on a par 3 can be over in less than an hour.
Beer brewing - always rewards patience and deliberateness.
Ever since I picked it up when I moved to Hawaii it superceded all of my other hobbies. The payoff for improvement is so great, and even if you don't have a great session, you're out in the ocean.
That next to enjoying time with my wife and kid; reading and playing tennis.
