I don't have any habits, however I do certain things in the same way or mostly in the same sequence because it makes sense to do so.
For example, I wake up, I dress up, I turn on my PC, I heat up some water. It makes sense to do so, and I do it in the most efficient and time-saving sequence every morning. If I had juice or something bottled, I wouldn't heat up the water. If I left my PC on, I wouldn't turn it on, if I slept with my clothes on, I wouldn't dress up.
I don't hate doing all that every morning, I find it enjoyable, as I do it efficiently. I like efficiency and I respect it; efficiency to me is very important. However, I know people who hate getting up, dressing up, making coffee or whatever the fuck they drink every morning, etc.. I can't understand it - if you hate it, why do it?
I don't think I have any other sequential activities. Except most of the time launching my browser, file browser and sometimes mail client. That's not always the case, however.
