Deep time is when you don't perceive time as passing. Prayer and meditation make some people feel "deep time." This is what medieval people experienced, probably because they were "task-oriented".

Time management is important when you want to coordinate the actions of a group of people. The invention of the steam engine brought about the industrial revolution. But it's hard to imagine the Industrial Revolution taking place without clocks.
Workers were paid for a day's labor or per piece. Today they are paid by the hour. And the business owners who can get the most out of their employees in the time allotted will make the most profit.
We used to think that time is what life is made of. But now it's considered more of a resource. This puts pressure on us to put this "resource" to good use. It is believed that managing and controlling your time is critical to living a meaningful life.
We try to cram as many chores into our lives as possible so that we can enjoy them someday. Instead of experiencing the present, we experience everything in terms of potential future benefits. Guaranteed to miss most of the things you want to do. Whenever you decide to devote your time to something specific, you sacrifice everything else you could spend your time on.
Instead of planning how to use your time, let the time use you. We can use our time to respond to the needs and circumstances of the moment. We can allow ourselves to be part of a community and let our social life dictate how we spend our time.
