Not sure if it's an "age thing" but I totally believe in creating your life in such a way that it IS your dream.
People so often talk about "their dreams" like they are this external "other" thing, like a pair of shoes. But your dreams are part of YOU, part of your energy. Even if you can't have your dreams "in this moment," you can still create your life in such a way that every step you take while doing something else still is a step into your dreams... and what that means is that when opportunity comes knocking, you're ready to TAKE it, not just stand there looking at your feet, mumbling "errmm... I'm not quite ready..."
