Happiness is defined as absence of sadness. It's you who brings either of them in the light.
Yes. You can do it. It can be done.
Not really the happiness part, it's how you choose to let life affect you.
No, what whacko said that? They need to be dropped in the middle of the African desert, without any food, and told "Ok, choose to be happy!" Although, I do think that over coming one's depression is a choice.
defenttly ...You can choose your emotions. True happiness comes from within, it can't be forced by outside forces. So how do you choose happiness? The same away you choose to smile or choose to wear a certain outfit. You choose it because that's what you want to experience in your life.
Indeed it is.
Nope, your circumstances can take away your happiness. Happiness can only be a choice some of the time.
