If these aren't words of wisdom, I really don't know anymore.
Seriously, the more I think about it, the more I realize how true and meaningful this quote is. I completely agree with mister Dyer but it is -of course- so much easier said than done to change your vision, your perspective.
We all have our norms and values who make us as an individual and that isn't something you can change in a second. It asks lots of courage, definitely when it's about something big/serious.
Don't we all have a vision that we 'need'/want to change? I know I do.
