No matter how well you think you carry yourself, if you do not value yourself it will show. And you'll be treated by what people perceive you as. know who you are and be confident in it. know your worth and act on it.
"Happiness is like a butterfly, The more you chase it the more it will elude you. But if you turn your attention to other things, it will come and sit softly on your shoulder." Just let it come to you & know you are enough, you are your happiness ♥
Be confident. Too many days are wasted comparing ourselves to others and wishing to be something we aren't. Everybody has their own strengths and weaknesses, and it is only when you accept everything you are - and aren't - that you will truly succeed.
