If someone told you that your shirt was ugly, would you wear that shirt again? What about if someone told you that your voice is weird, would you want to talk again? Or if someone told you that your smile is awful, would you want to smile again? Some would, some wouldn't. Some would change to please, some would hide and some wouldn't care.
Sometimes we let the negative thoughts take over our life. Whether it be the way we look, the way we dress or the way we act. Sometime in your life, someone is going to tell you that you aren't good enough or you aren't worthy enough or you aren't pretty enough. At the end of the day, who are they to tell you that you're not good enough, who gives a sh*t what anyone says. YOU are YOU, being who YOU are is good enough, YOU shouldn't change for anyone.
"A positive person anticipates happiness, health and success, and believes he or she can overcome any obstacle and difficulty."
Positive thinking can happen with self talk, talking to yourself. As weird as it sounds, it can make a difference. Instead of waking up in the morning and putting yourself down. Look in the mirror and tell yourself "today is going to be a good day", "I like how my eyes look today", "My hair looks good today". Saying small positive things to yourself can really make your day a little brighter. Instead of telling yourself that you can't do it, tell yourself that you can! 99% of the things you worry about, never happen.
It's so easy to put yourself down and back away from something that could lead to something even better. Say YES to opportunities, think positive and positive things will happen :)
