If you can take your mind off the small things, you can use that brain power on the larger things that matter.
I think that's why the smarter guys in the room have what some call a 'signature look'. Jobs wore a black turtleneck and jeans all the time. Sure, his look changed over the years, but in his later career, he pretty much wore the same thing all the time. We all laughed about how many of a certain thing he had in his closet, but think about it. He never had to sit in that closet and think about what he was going to wear today.
When I go shopping, if I find something I like, I buy three or four of them in different colors. They fit nice, they look decent, and I really don't want to put a lot of brain power into it. My concession to you is the different color part, because I'd be perfectly happy to buy all black and grey (or silver) everything. I figure after three or four days, you'd all wonder if I ever did laundry.
It's just another form of automation, which I'm a huge fan of. The more things you set up to just happen, the less you have to actually worry about. When these little headaches go away, it frees up your time and attention to focus on the important stuff.
This will take an investment in your time at first to set things up, but it's well worth it on the back end.
So, think about the stuff you'd rather not think about anymore, and make a plan to set it up.
Then, go do it, and get back to work on your ship.
