It takes up to 25 minutes to get in a productive state after checking emails.

Keep your email closed for the first 30 minutes of your working day. Switch off email notifications while you're focusing on work.

Keeping too much information in your head can make you think you are in control, even when that's not true.

Keep a notebook where you can empty your mind from any ideas or to-dos, before starting the day.

Multitaskers perform generally worse in tasks than those working sequentially.

Plan your day ahead for maximum productivity by allocating 40 minutes blocks for single tasks, with 20 minutes blocks in between to work on miscellaneous tasks.

Standing rather than sitting can help you gain more control and power over a situation.

Go for a walk or use a standing desk for the first 10 minutes of your day.

Drinking a coffee to kickstart your day is a bad idea because it interferes with the time when the stress hormone cortisol is peaking in your body.

Only drink coffee between 10:00 AM and noon or 2:00 PM and 5 PM, when your cortisol levels are lowest.

Exposure to light early in the morning is beneficial for your mood, alertness, and metabolism.

If your desk is near a window, open the blinds or curtains each morning lo let light in. If that is not the case, consider investing in a SAD lamp.

Block out meeting-free time at the start of every day in your calendar, accepting only the most unavoidable meetings.
