At first it's difficult for any one to accept a change as normal tendency that we don't accept changes happily but once when we realise that this change is benefiting us we don't only accept it but ask others also to accept it.
Consider the case of mine, we are going to shift in a new house very soon but we are worried how the neighbors will be. But I know that's temporary we will adapt ourself in that environment once we move in, with the time.
That's not very easy though but being mature we have to accept it and move ahead in life.
" It is better to be hated for what you are than to be loved for what you are not" ... Andre Gide
Everybody is busy to manage their own life. There are many things to do in our daily life and few people have the time to think of any changes. Those few, thinking of changes, plan something effectively to show the rest how it is going to affect their lives. To concentrate on anything, one needs to pay attention to stay focused. So, when you notice something that requires a change, you communicate your views to others to let them know. When they find it useful they also spread it to some more. So, it's a cascading effect and is essential for every movement to succeed.
"Life is easier when you enjoy what you do"
When everything is going on in a settled way probably many people don't want to disturb the situation by accepting the change. But people who are ready to experiment and try to see that there will be some development by making some changes will try to do that. Once they are successful many people will follow them.
