People are ships couldn’t really be more opposite, if you’re taking it for its literal meaning. Put the literal meaning aside for a minute and it quickly becomes obvious that if we feel too comfortable we’re not going to achieve anything more than what we’re currently achieving. If we don’t push ourselves to try new things then we will sit stagnant. Humans are made to push boundaries, achieve new things and go fourth and defy gravity. While sometimes it might be easier to sit comfortably it’s going to be more rewarding to get out of your comfort zone and achieve something you never thought would be possible.
