Highly productive professionals share the same clusters of habits:

One research survey, involving 20 000 individuals from six continents, wanted to find out why some people are more productive than others. 

There are noteworthy differences in how women and men managed to be productive.

• Most of us look at emails every 3 - 5 minutes. Instead, look every hour or two, and then only at subject matter and sender. 
• Answer important emails immediately instead of flagging them.
• Managing incoming emails needs to be paired with other, more big-picture habits. 

Age and seniority highly correlate with personal productivity.
