1. Plan out your day
Before you sift through your hundreds of new emails, voice messages and start on that task you've been putting off all week, grab your morning coffee and set out a schedule for your day. Seems simple enough but this is the number one rule to increase productivity.
Set a timer for each of the tasks and layout when you're going to get each task done by. e.g.
8.30-8.45am - Plan day
8.45-9.45 - Reply to emails, phone call, chase up supplies
9-45-10.30 - Go over blueprints for the Jones' job
10.30-10.45 - Morning break
