Well it depends on what I have to do since I like to have my things planned in a calendar and use reminders to focus during my day. I can handle surprises in my schedule just fine but it sometimes ruins my productivity. Another thing is if it is early in the morning or late in the evening, I think I can do most things both times but I am worst at the morning I would say since I can be a sleepy horse as my energy levels can be very low at times if too much have happened lately.
