I find it very easy to be wasteful. I can spend money far easier than I can make it. If I let it, my house atrophies and falls apart so that water and energy leaks away. Netflix will line up episode after episode so that time ticks away.
Waste happens when I have plenty of choice.
The opposite thing seems to happen when I think I have less than I need. If I am stretched on a job I can put in superhuman efforts and meet a deadline. If I am running out of money, I can make ten bucks last for a long long time. If I have a clear idea of where I am headed, resource constraint is not so much of an issue. Sometimes it is liberating and let’s me achieve more than I set out to achieve.
