'How we spend our days is, of course, how we spend our lives.' ― Annie Dillard
Todo apps always turn into graveyards of good intentions
New interesting books end up unread on your shelf
Constantly overworking, yet always behind schedule
Important tasks rush in on the last day, even though you had months

The Theory of Constraints

The output of any complex system is limited by its single biggest bottleneck
The brain consumes up to 20% of the energy used by the human body
Limited amount of available cognitive energy is our brain's natural constraint
Conserving metabolic energy is our brain's survival mechanism
Our habits determine how wisely we spend our cognitive energy

Our mind defaults to the path of least resistance

If we need to think about each task, our brain just puts it off
