More time, more than time management, is a function of choosing to waste time and choosing to not waste time.
When you schedule your time to waste, you get more focused in your time to be more productive.
When you schedule your time to be focused, you distance the things that distract you.
Rinse and repeat, for everything you do.
Time management, is simply an art of choosing balance.
Every single day. Even when (especially when) it is easy to lose that balance.
