"Don't live in a shitty place to live filled with bike thieves."
I moved to a much better place to live, and I rarely lock my bikes anymore. I'll toss a cable lock through the frame and front wheel at church, or cable lock it to a parking lot sign or something if I do anything. It's just not an issue in large parts of the country.
If you live in an area with aggressive bike thieves? Ride a crappy looking bike with halfway decent components, insure it, lock it the best you can, but don't get attached to it, because someone, somewhere, needs a hit of meth more than you need your bike.
