Any motivational quote telling you to reach higher is in essence telling you to be discontent with where you are. I am not sure why people are always telling people they are not good enough? Why not motivate people to be the best they can be in the present?
We live in the present so do what you are doing right now to the best of what you can do it. If you are on the couch right now make yourself the most comfortable you can. If you are working work as hard and as smart as you can earning a full days wage. If you are shopping then….. Do you get the message?… It’s not about chasing something you don’t have right now it’s about appreciating what you have, where you are and what you are and utilizing everything you have at your disposal to maximize your time, multiplying your effectiveness a hundredfold by being in the moment.
