Being strong in no way means that you are impervious to getting hurt. Being strong means knowing that you’ll hurt, and knowing that you will be alright again, hopefully with more knowledge than before.
Being strong means not allowing the fear of being hurt to stop you from fighting for what you believe in; from pursuing the things that make you happy.
And along with everything in life, it is a balancing act: it is a fine line between being strong and being foolish.
