We are so risk-avert in human nature that the best part of life which can only be experienced in the uncharted waters is so commonly missed. There are as much fear and suffering as wisdom and growth through the journey of uncertainty. The author of this post is not saying this as a spectator but from his first-hand experience. The young chap in the photo has gone through two unsuccessful surgeries and still fighting against the difficulties in life with gusto and his combative best, with the author a backup and companion.
If you are in a difficulty or two, stay calm and make sure that you know life is unfair – that's why you're not alone in fighting through it. We all are putting up a fight.
