Chamunda Mantra Credos – The way to success is to believe in yourself and your abilities. The world does not know what you will be in the future, and it is the future that you will make. Therefore, it is better to believe in yourself and do the work that you know you can do, even if you have not done it yet. It is only through your own efforts that you can achieve anything. You should not give up on your goals just because you have not yet achieved them.
