Minimalism
Do you really need it?
Or do you really just want it for some particular reason? Everything there is requires cognitive energy to deal with. How much energy can you spare? If you don't need it, get rid of it! Suddenly there will be plenty of time for joy.
The most precious commodity?
Time. The very scarcest resource that cannot be purchased. Use it wisely (Nobody on his or her death bed ever said: 'I wish I would have bought more stuff!').
Keep it simple stupid!
Beauty is simple. Complexity is ugly. And time consuming. All things in nature are plain. It is us humans which make things hard. Don't be one of those humans.
Go with the flow
It is futile to fight the current. Life is about gently adjusting the course to stay afloat and not get grated on the spiky shores.
