There will always be people whom you interact with that haven't yet learned what you have learned, that it is your spiritual responsibility to be happy and blessed.
The beauty of truly learning something for yourself is that no one can take that learning and that knowing away from you unless you choose to let them. The moment is the most important to remember your responsibility to your happiness is the moment that it is the most tempting to feel guilty about it or doubtful about it. The judgment, opinions, and reactions of others can act as a sort of amnesia for your truth if you let it in.
Have compassion for the people who have not learned what you have learned. This will help you remember what you know. Judging anyone who has not learned what you have learned will have you forget what you have learned. Remember what you know today and receive what you are meant to receive.
