Life is the second name of Try Try and Try. None has achieved a goal in his/her life without struggle. It is also true that Failure and Success go side by side but those get triumph who keep on struggling without the fear of being failure. So, my take on this quote is one should keep on trying until his/her last breath. Believe you none can stop that person from achieving his goals of life:)
Thanks a lot the beautiful Soul Tomas for putting some positive energy through this quote <3
