YOU DON"T - you don't have to because you march to your own drummer.
When you do...You are independent of the good opinion of others, you don't need to explain yourself because it's won't matter what others think of you. It's what Deepak Chopra (and eastern philosophy) calls 'self referral' - the reference to the self comes from the inside and not the outside.
I've been where you are and at first it's very frustrating beacuse you want people to understand, but it's hard to explain 'why' you are marching to your own drummer. Just let it go! you do not need people to understand - you just need to understand it for yourself and only when this is enough for you will you truly be able to march to your own drummer.
