If you wish to improve your human qualities, you will need to take certain steps to walk towards that goal. The 1st is a mindset focus that you wish to be virtuous. The 2nd is words & deeds to match that. And lastly you must spend sufficient time with people of that lovely, selfless category so that their fragrance can be transmitted to you.
Associate with good people & you will become one of them !
