Single mindedness, determination, dedication, self-belief and the inability to ever give in are what distinguish people who do great things with their lives from those whose dreams die with them. When you have great perseverance you take into account what others say but you don't let it rule you. You remain true to your vision.
Walk Your Walk
You have to walk your own walk in this life.
And as you are traveling down your road;
Don’t look down at your feet.
Keep your head up and your eyes focused
on the road that reaches your goals.
