It's not about chasing new information and jumping from one thing to another endlessly and frivolously.
It's not about using fewer things so that you stay within a certain comfort zone.
It's about going very deeply into the fewer things that you have.
This way you can understand them and yourself incredibly well without distraction. Then, although you have fewer things, you use them to do a lot of different things but incredibly well. Like a craftsman who understands his tools, and how to use them to create whatever he wishes.
An interesting thing a friend told me about his old Chi Kung teacher, who also happens to be my Doctor. This teacher said; "In life you learn a,b,c,d,e,f,g,h etc..., But then discover you only ever really need to use a,b and c...But many times in many different ways that yield whatever results you wish"
How well you use these fewer things depends on how closely you study them and yourself.
...My Doctor is a cool guy :)
