Most of us have the misconception that our destiny is not in our hands but it is decided by some omnipresent forces present in nature. People rely on Karma so much that they forget the purpose of their life. A belief in Karma is not bad but thinking that whatever is happening in your life is because of your Karma is just rubbish. A blind belief in Karma will definitely destroy your life before you can realize it. Be bold enough to blame yourself for the wrong decisions you had made rather than blaming Karma. You are responsible for your present state of mind.
Potential
We all have the potential to achieve whatever we want but we seldom realize it. To activate your potential, first you have to decide the purpose of your life. Once you have decided your purpose, focus your immense potential on that and this will generate the energy required to fulfill that purpose.
Faith
You cannot achieve anything in life without faith. You may have faith in God or your fellow human beings but faith in them is not going to help you write your own destiny. The only faith that will help you is faith in yourself. Believe in yourself and your abilities. Your trust in yourself will boost up your confidence and will diminish your weakness. Try to live without weakness and live by what you believe.
Energy
When you put faith in yourself, you will feel surrounded by a surge of energy. Then you will feel that you don't need any rest. This non stop supply of energy keeps on increasing as you achieve one purpose after another in your life. Fools take rest when the energy is fully charged and then blame Karma for their destiny. Don't waste your energy on self centered ideas and purposes because it will consume a lot of your energy and you will get tired soon.
Ego
A little bit of ego is fine to maintain your self esteem but try to avoid it before it physically transforms you into some kind of monster. Ego is like a termite which will eat you from within and before you can realize it, you will be hollow. The burden of ego on your shoulders will decrease your energy and automatically you will get tired very fast.
Life is an enigma for those who can't understand its purpose and for others it is a beautiful journey because they are moving in the right direction. Literally your destiny is in your hands, don't wait for it, just grab it.
