Eleven Ways To Improve Your Productivity

Select the three most important things to do each day and do them first.
Schedule your time, even downtime and stick to your schedule!
Capture new ideas on a list and then set it aside. Review it weekly during scheduled time.
Eliminate distractions (i.e. email, messaging, social media).
Place your phone on forward and return calls at scheduled times.
Keep meetings and conversations brief and focused on the point at hand.
Askew meetings that do not provide value.
Delegate anything and everything you can. If you have no one to delegate to, ask a spouse or hire someone. Your time is too valuable.
Use closed ended questions to quickly bring unexpected interruptions from others to conclusion.
Use timers and alarms to keep you focused on completing tasks on time.
Turn off bells and chimes that remind you of new email messages.

And here is a bonus for you. Hold yourself accountable. How you manage your time is completely up to you.
