Actually, I don't think that not caring is a way to be happy. I think that's just the way to be indifferent, which isn't the same thing. <br />
I think being happy is about appreciation for what you have. Focus on certain things rather than other things. Loving when you can and receiving love that is offered to you. And trying to make the best of who you are and the potential for things around you.
Find something you enjoy doing and do it.
Stay in bed with a ***** and attend to its needs.
setting goals and working towards them. helping others.
Finding quality people with similar values. Their opinions would matter, but because of mutual respect.
You do what makes you happy as long as it is legal.
and doesn't hurt anyone else ........
