If a species is diverse, it can survive and prosper. If a species is homogeneous, it is vulnerable.

There is no shortage of time. In fact, we are positively awash with it. We only make good use of 20 per cent of our time.... The 80/20 principle says that if we doubled our time on the top 20% of activities, we could work a two-day week and achieve 60 per cent more than now.
