In your journey to success, you will have to be strong. Strong enough to not let the words of a group of people, called the naysayers, affect your momentum and goal. They are the ones who cast doubts and negativity at you. Before you let them get to you, take notice, most of these people are not actually successful. They would rather hide behind their keyboards or lack of a meaningful purpose in their lives and bring others down to their level. Those who are successful would know better than to bring someone else down. Having been through what that success journey required of them, they would understand the effect that could bring on someone who is starting out or on his/her way there. So do yourself a favour, get a thick skin. You do not have to be rude. Give them a smile and get back to working hard.
