Many times, how you think about the things holding you back hold you back more than the things themselves. For example: criticism.
It isn’t criticism that holds you back, it’s how you choose to think & react to it that does. Always remember that how you choose to respond to criticism and negativity is a choice.
Ignoring criticism is an option that too few people take advantage of. The more that you consciously disconnect yourself from modes of thinking that hold you back, the more you free yourself to move forward unhindered.
