The most important and valuable resource in the world is time. It is limited and non-refundable. You can never take back the time you lost. Time spent productively is valuable. Every second, every minute, every hour dedicated to something that could improve your status whether that is physically, mentally or financially... expect something good to come out of something you made time for. You have to choose wisely where to spend your time because making this choice, you will be trading an opportunity for another. If you decided to spend this time lounging around instead of dedicating your time to improving yourself then you are losing the chance to be a better version of yourself.
