How do you manage your time at work effectively?

Multitasking at work is nothing new, but finding ways to better manage time can be.  Workloads are rarely consistent.  Most jobs require multiple tasks to be completed by a deadline, whether by end of day or EOW, etc.  Often workdays include addressing emails and attending office meetings, too.  Add interactions with your team for a quick chat, laugh or break and you might ask yourself where did the time go?
