Don't view your actions in a format just for yourself.
Your actions and the result you are striving for will trigger a series of events not only for your family, but also for your friends and even those you don't know yet.

Think about it and keep fighting.
I'm sure you've already played a meaningful role in someone's life, just as someone has influenced your destiny.
