Also known as Eclecticism. Having multiple philosophies or
religions.
If others have already made their own philosophy, what’s the point? The
point is that one philosophy certainly won't fit all. The closest one is
pragmatism,
but humans may also have social needs and cannot simply "do what works"
all the time.
As such, no single philosophy fits all people.
So one needs to weigh, mix, and match daily activities, depending on the
presence of others and many other factors, etc. Experience helps here,
and also do a cost-benefit analysis to see what a
philosophy can contribute and is worth following or not.
The weightings you give to each philosophy can be arbitrary, and it can add to decision fatigue, as you add more and more philosophies...
