Don't listen to what anybody says except the people who encourage you. If it's what you want to do and it's within yourself, then keep going and try to do it for the rest of your life.

This quote means that you should only listen to people who motivate and inspire you, and not those who try to tell you that you can’t do something or put you down. If you have a dream or a goal that you really want to achieve, don’t give up on it, and continue working towards it with dedication and perseverance, no matter how long it takes.
