Some of these things are only possible in certain position,but rough ideas: 1) reduce number of meetings to minimum. 2) in the meetings, know why you are there and try to stick to the agenda. 3) sort out things you need to do by priorities ( low, medium, here and now). 4) Check if your to do list is balanced: e.g. not all tasks are 'here and now'. If it's not balanced,raise it with management or try figure out yourself why that's the case. 5) Turn off distractions: email, text, chat,etc. Leave 1 channel ( phone?) open for emergencies. 6) Inform others where you are and what you do. E.g. : 'I'm in a zone between 9am-11am, don't bother contacting. 7) Learn to be OK if you don't do everything you were supposed to. You aren't in a hospital, nobody's going to dye. 8) Aim to complete 3-5 things in any given day. No point to commit to 20 if it's all going to be half baked. 9) Learn stuff early in the day- much easier than towards the end of it. 10) Take short brakes no matter what: even 5 min walk down the corridor is useful.
