We spend a lot of our time putting things off until tomorrow, but the problem with tomorrow is that we never get there. If we form a habit of putting things off then the habit means we perpetually avoid doing the thing we need to do.
For all of us, we have a day which is our last day and so much that would benefit the world goes undone, because it was put off until tomorrow.
If you want to make the world better, if you want to make a difference, then do the thing you are scared to do, do it. Go all in and do it. The worst that can happen is that it doesn’t work or you need to make it better. Whatever may happen, it will be better than never doing it at all.
Go and make a difference.
