Act as if what you do makes a difference. It does. – William James
So obvious, isn’t it? When I first read the quote, I was like “D’uh! Obviously, every single thing you do impacts someone!”
But when I reflected, I realized that may be we do the “bigger” things with this attitude – like working our ass off for someone else, stressing over their judgement about us, analyzing if the world would approve of our actions, being politically right, charity of money or time (because it makes me feel worthwhile), etc.
In doing all of above, we put forth our best behavior for the entire world, and save our worst (including what we get from others), for probably the most important people in our life. This is because we take them for granted, ourselves for granted.
Things that actually make a difference, like smiling to the mirror in the morning, will make a world of a difference to the most significant being to us – OUR SELF. And if we are able to do that, the rest is taken care of anyway!
