… learn Self Management.

Time management presupposes you can make time do something for you. In reality you are managing yourself, not time. How can you manage time? Time doesn’t do anything for anyone, it just goes forward, all the time, non-stop, no comprise. You can’t make it do anything else.

This might just be a semantic details, but I feel there is fundamental difference to learning self management rather than “time management”, it’s the fundamental difference between being efficient and being effective.
