That quote speaks volumes to me! I find myself now regretting the things that i never tried to do in the pass. Like honestly if I tried some things that I was scared to do I might never be able to try them again.
A silly example is when I was a kid I was scared of flying the big jumps on my pedal bike and wouldn't dare to try them. But looking back on it now I wish I have because If I try to do them now i'll probably be off work for a week or so if I fail the jump
