“Learn to be alone and to be yourself, don’t let the company of others define who you are.”
My own take on the “don’t let others define who you are” quote; we all need at least a soft whispering voice of our own if we are to leave a trace in this world. Socializing and hanging out may have benefits of their own, but so does some alone time. If you spend your whole life following others, you’ll never give yourself the chance to learn and experience what your soul craves to do.
Make sure you step away from others once in a while, and do something on your own. Something you always wanted to do. Something you love. Something that’s you.
