Strange Behavior

Here is the wide question !!!
Why do people behave and act at the same thing ?
Why do people shear the same action while they are eating, talking, and thinking ?
For example why do people eat by right hand ? Why do they eat egg and beacon in the breakfast ?!
Let's eat rice instead in the breakfast instead of egg !!
So my idea for this post is people imitate the same behavior from other people naturally
Why ?
We have our brains and our mentals. Why we can't behave as we need not as other people do.
There is no knowledge or any concept of our behavior or action 
Always and every day we do the same thing as the other people do and that what established the stupid people whatever rich or poor people.
We have to behave as we need to do not as other
Let's try to eat by left hand, let's try to sleep on the blanket and cover ourselves by pillow, let's sit on the table instead of chair, let's talk about ghost instead of human.
As a result I hope now my idea is clear to you.
Simply try to make yourself strange with new behavior that never ever someone has done that before.
You're as you're, don't make yourself simply, always make yourself strange to have the ability of changing every day
Thank you
