Do you tend to doubt yourself rather than believe in yourself? Are you always questioning your worth and downplaying your abilities? There was a long time when the lack of belief in myself was a major factor in my life. I didn’t pursue an ideal career, or start my own, but now i'm ready. There may be days when you get up in the morning and things aren't the way you had hoped, but its okay.
Sometimes people come into your life and you know right away that they were meant to be there. To serve some sort of purpose. If you don't believe in yourself, then it doesn't matter how talented you are or how big your dreams are.
