My wife whenever I'd go off to work and I'd be kind of anxious she'll say 'Remember have fun.' Oh I forgot thanks for the reminder. Because sometimes we do forget. We take it all too seriously and there's a lot of joy to be had wherever you are.
But it's a journey and the sad thing is you only learn from experience so as much as someone can tell you things you have to go out there and make your own mistakes in order to learn.
