Who cares what anyone else thinks, if in the end they will end up supporting you and agreeing with you!
Even if nobody takes you seriously, just believe in yourself and do what you think is best, they will end up believing in you..
DON'T LISTEN TO THOSE WHO DON'T BELIEVE IN YOU
It's hard to believe in yourself when people tell you that you can't do something. Nobody wants to hear that they won't be successful, especially if it comes from someone who is supposed to have your best interests at heart. However, sometimes this isn't true and there are people who will simply not believe in you no matter what. You can choose not to listen to them by simply believing in yourself; that's all you need!
SOMETIMES PEOPLE WILL SIMPLY NOT BELIEVE IN YOU. ACCEPT IT!
Don't let the negativity of others get you down. When someone doesn't believe in you or your abilities, don't let that stop you from doing what you want to do. Don’t let it stop you from believing in yourself and who you are as a person, no matter what anyone else says about it! Know that there will always be people who have something negative to say about everything and anything—the world is big enough for all kinds of different people with varied interests and personalities, so try not to take it personally when someone disagrees with things about yourself or life in general.
JUST BELIEVE IN YOURSELF, THAT'S ALL YOU NEED.
When you're working on something, other people's opinions can be incredibly distracting. It's easy to get caught up in what they think about what you're doing. But their opinions don't matter!
You have your own life, and it's important that you stay true to who YOU are—not what others think of who YOU are, or how THEY want YOU to act.
The most important thing is: Just believe in yourself, that's all you need.
WITH TIME, YOU'LL END UP PROVING THEM WRONG.
If you keep working hard and pushing through, the haters will eventually realize that they were wrong. They will end up supporting your success, believing in you, and admiring whatever it is that you do. You will be happy and comfortable being yourself.
Be positive and persistent, because if you keep telling yourself that you can do it, then eventually you'll find a way to prove those naysayers wrong.
