What beliefs you hold as true that are holding you back from what you want

Belief is the software that runs your life. If you believe in something you act according to that belief.
If you believe that people are untrustworthy, then you will not trust people, you will always doubt their sincereity until you are proven wrong.

If you believe that no one would hire you for your dream jobs because you don't feel you deserve it or will not be able to do it, then you will not apply for such positions and no one will hire you because you would project your own deficiency during the interview and the employer would not have confidence and you and you would not get that job.

If however you believe that you are capable of doing the job, learning the ropes in no time, bursting with confidence that you are worthy of this job, that's the energy you would take with you and people will feel and before you know if you are offered the job of your dreams.

Take that step for your dream.
