If they are disrespecting you.. just shut up and say nothing. But go home and work hard, become successful, make success as your revenge. Remind them who you are, remind them who is the real boss in town. Show them your true power, show them the real you.
Wake up and reclaim your throne, bring back the days when you are dominating and eating the competition. The time of being weak is over, it is time to use all of your strength and bring yourself back to the top. Because if you will not move now, they will disrespect your brand forever. Show them what you're all about, show them your true colors, make them know your true level. Make them know how strong you are and how weak are they.
