Many of us would simply prefer to “Get to Work” and start doing things, but we intellectually know that it’s important to create a plan so we can prioritize then execute most effectively.

• Create regular habits and routines that keep you and your team on-track. 
• Build motivation through disciplined execution.

Marshall Goldsmith does a great job discussing these in his book Triggers, including 6 Daily Questions we should all ask ourselves.
