This is about doing something you like with people you respect. Develop your talents by constant use and discover new ones to try out with other people and make their lives different and better. If we travel in the right direction and apply our wisdom wisely then Happiness happens.
This is down to you, it is not about other people make you happy (or sad). It is about how you respond to them.
What makes you happy will change with time, so embrace change, remain positive about it and happiness will flow.
