You need to be happy.
You deserve to be happy.
If your not happy how do you spread joy to others.
So it’s simple, be selfish. Do things that make you happy.
Take time for yourself, so you can do the things you love, the things that bring you joy.
Then and only then can you be present enough, in the right frame of mind, to bring joy and happiness to others…it will be natural and happen all on it’s own!
