Mark Twain Quote

I've heard this quote before and was thinking about it whilst running today.  Although it doesn't have anything particularly to do with either cycling or running I really like it so decided to share it.  We all have fears in our lives, I know I do, but how many of them ever actually come to fruition?  I would suggest not very many.  What a waste of time and energy.  I for one will certainly try to remind myself of this useful little quote more often from now on:

I am an old man and have known a great many troubles, but most of them never happened.

Mark Twain
