I've started to adopt a similar practice, although a somewhat more flexible one.

Whenever I'm at a restaurant, or ordering food for whatever reason, I will check the menu for an item that prominently contains mushrooms. If such an item exists (and it doesn't sound awful or ridiculously expensive), then that's what I'm getting. Decision made.

I started doing this mainly because I like mushrooms, enough that it felt like a really easy way to hand off decision making. It's also good in that, unlike the above, I don't get just the exact same thing every time (although mushroom burgers are starting to seem pretty same-y).

One thing I like to do, especially when I'm too tired or fuzzy to spend my limited energy on a large number of choices, is to wait and see what others are ordering and then pick from those options which you like best.

Also reduces the odds that you'll be looking at someone else's plate thinking "I wish I'd have ordered that instead" :)

What about trying new things, experimenting with life?

I think the idea is to remove decision making from things you personally don't care too much for to give you more time to focus on those decisions you do care a lot about.

Decide that you will always try something different from last time.

I always try to identify items I wouldn't be able to get elsewhere. For instance, if I want to order a beer I go for those that are in limited stock or from a local microbrewery. Spice of life and what not.

Um yes, go for it? :)
