Managing your time is very important since with time spend in the office and time spent on travelling, most of us rarely get time to get down to completing some of the important chores that we might have to get done on time.
Also, productivity comes naturally to those who have the habit of doing thing according to a routine. Which is why, it is advisable that every night people should set aside some time to think and plan their next day.
Also, setting out which clothes you would wear to work the next day saves you a lot of time in the mornings as well. Also, productivity comes from the fact that you also spend some time on yourself be it on fitness or even on learning a new hobby.
