A great turbo thought I had tonight:
When contemplating purchases or investments, try to honestly ask yourself — “Will this give me an (unfair) advantage in life, or not?”
For example, buying that new luxury car (if you already have a car) won’t lead to any meaningful advantage. Having an iPhone is certainly superior to having an Android phone, but having the most high end or brand new iPhone won’t give you a meaningful advantage in life compared to a standard iPhone.
Similarly speaking, shooting with a Leica won’t give you any meaningful advantage in life, in your photographic life.
So try to think hard and deep — don’t get suckered by things which you perceive won’t give you a meaningful advantage in life.
