I agree with you. Ironically, the more attachment people have to linear time, or in other words, the more people cling to the "time-is-scarce" mindset the more they are are actually wasting the time they have. Whereas when we become more detached from linear time, more multidimensional in our mind, we increasingly feel like having more time thanks to realising that there is only an ever-expanding present moment. In this state, nothing we ever do is ever wasted, even doing "nothing" is completely worth it. Effective time managment at its peak, I would say. :)
