I find those few minutes while waiting for the car to warm up to be a good opportunity. Driving seems like a good time sometimes too, because I start thinking while I'm driving, and either remember something to pray about or just remember that I forgot to that morning.

I heard something today that I thought was helpful. If you go to the doctor, you don't just walk in and say I'm sick, please make me better, and then walk out. If you take your car to the shop you don't just say please fix my car, it's broken. You take the time to tell them what is wrong and how you know, and discuss the problem, and you listen to their recommendations and take some kind of action. So maybe when we pray we ought to discuss things a little more, and remember to listen for an answer, and decide what steps we will take from there, come back and talk about it again later after trying it, etc. We could at least put as much thought into prayer as we would our other daily conversations.
