That was certainly the secret for me. I kept track of every obstacle, and eliminated them one by one, so that there was no need to even decide in the morning.
I set aside a place in my house for all of my cycling , so I don't have to look for it. I check the weather when I get up, so I can grab the gear that I need for the day. I hauled a bunch of spare stuff to work, mostly worn out gear that I didn't need at home any more, including rain jacket and pants. I frequently check the condition of my bike, so there are no surprises during my ride. And so forth.
