Ambition with detachment
How about being laser focused on your goal and your task at hand with no attachment nor worry about the result?
This is the method to apply the doctrine of ‘Karma’ to your life.
And if you look deeply into your life, you will realize that this expression will fit well with your state of being each time you accomplished things that you are now proud of in your life.
Think about it. Work on it. You will see success. You will attain inner stability.
