"You are never too old to set another goal or dream a new dream" - C.S. Lewis
AND:
"A vision's just a vision if its only in your head. If no-one gets to see it it's as good as dead." Stephen Sondheim (Sunday in the Park with George).

So what's keeping you from making your dreams a reality?  Are you finding obstacles that give you a reason not to get going? What's that about?  Be brave and take the first step. Make a plan, and tell people around you what you are going to do. Ask for support, look for actions that will take you towards your goal. It doesn't have to be big steps - in fact lots of small steps are good for getting momentum going.  Those gold medal olympic champions all started somewhere!
