Happiness flows through you, you don’t get it from anything outside.
Everyone wants to be happy and whatever we do is to be happy and something which is not giving us happiness we never want to do it. We always claim that doing this makes me happy and doing this does not make me happy. But the thing which is making you happy might not make someone else happy. Going to party can be a thing of happiness for you but may not be for your friend. So it clarifies one thing that the party is same but the persons are different and that is why the feelings are different, so it does not depend on the party but it depends on you. So to be happy with something or in a particular situation depends on you.
Now the main point is we all want to be happy but do not know how to be happy. Situation changes and things too, what does not change is you, so to have a constant happiness we need to have the happiness within us, so that it stays consistently. First thing you need to understand, you need to live in the moment of now. If you live in past moment or the future moment, you can never be happy because thinking about anything else other than what you are doing will always erode you of your peace and it will surround you with worries. You will be divided and if you are divided then you can never be happy. So be involved in the present and be there completely. Once you are involved into something completely, then you will be at peace and happy. Once you are filled up with happiness inside, then whatever you will do will also be filled up with your joy. No task would be tedious and it will flow into everything through you with positive vibrations. Through your work, this happiness will spread into everything whatever your work would be touching and everything around you will be flowing with true happiness. Once you start the chain of happiness, you will always be happy. So happiness flows through you not to you through something else.
