Why not change the world through Individual efforts?

Start changing one's lifestyle can totally change the world,

If we stop making excuses about If that person is not doing it, only my efforts don't work is the worst idea you can ever have, 

Imagine Columbus imagining of  an unknown world which people had found today,

If he didn't make the effort at that point in time by listening to someone's random thoughts the world wouldn't find it today,

Individual's change had to change the world in every forms nothing was ever discovered by a group,

Great things were always discovered by great minds and then put into an effort, either in form of groups or individuals,

Let's start making efforts and implement them without fear of the world to change the world starting by today.
