Time management is a myth. Now hear me out before you start freaking out. There is no way you can manage time. You can never increase a second or decrease a minute. But what you can do is you can manage two things. Number one is your attention. So whatever you are giving attention to, that you can do. And the second one is your focus. How can you keep you away from all the distraction? How can you not switch and do multitasking? If you can practice these two things, nobody can stop you from becoming the person you want to become and not having to worry about time management.
