Everybody has, had or will have confidence problems at some point in their life. That's simply how humans are. We get scared and insecure.
But life's to short, it's time to stand up and love ourself. Were stuck with ourself forever, so lets stop hating all our flaws. That won't bring anything good. Keep you head up, walked like your the most wonderful person, smile like nothing can bring you down. Nobody is perfect. Accept your flaws, learn to live with them. They are part of you. Do more of what makes you really happy, become a pro. Have fun. Smile. Focus on everything good about yourself because even if you hate who you are, you still got at least one thing about you that you like. Pick one, think about it when things get hard. You're beautiful. Stay positive, all the time. Nothing good happens from being negative. Be kind to others, they have confidence problems too. Look them in the eyes and listen to what they say. Be someone nice. Be curious. Learn new things. Do it for fun. Be confident, you're amazing.
See ya later <3
