Because if you are not there to live your own life, then who will live it for you when there is only one of you out there in the world. If you do not live your own life, no one will live it for you – don’t ever let your development and/or progress be halted because of a barrier in whatever shape or form it comes in. Keep moving forward and don’t look back because you have now crossed the bridge, you have swam the ocean and have made it to the other side. Don’t give up, otherwise your journey has ended and your chapter has now been closed. You are the only novel about yourself that exists in this world, you hold the pen to write it and the paper to shape it – if you abandon these instruments, then your story finishes there and your life has finished its course.
As I said, “Live your life because no one will live it for you.”
