Our belief system is usually the cause for the outcomes in our lives. It is unspoken. It may even be concealed from the rest of the world. But there it lies in our hearts and at the back of our minds. It may even differ from the actions we portray to the world.
For those whose reality is congruent with their belief system, life is good, at least compared to those who are not. The beliefs that tend to limit us from achieving our potential are usually buried deep inside us. And unless we face them head on, we will never be able to achieve our goals.
So what are your limiting beliefs? Write it down. Say it out loud. Confront. It is all just in your head.
