I have read the post Get Everything Done & Still Have Time to Play by Jackie Ashton recently and adopted some strategies into my process.
Before I plan the tasks daily by allocating them into time slots in a calendar, it is tedious and time-wasting. It messes up my agenda, which is intended only to contain the events that I must do on time. And it makes me nervous and exhausted to follow a pre-defined schedule every day.
My new process is much simpler. I review my life objectives first and group them into categories. Then I evaluate their importance in my current life stage and allocate my energy in percentage into them.
