Always be true to yourself. Generally speaking, I am.
I am who I am and I don't try to be anyone else. I do however keep my private life, private. I don't feel a need to broadcast to the world who I love and may sleep with. It's no one's business. Period.
Like Chris, I don't see this as a GLBT only issue. My friends come in all shape and sizes, interests, and beliefs, unlike the author of the article linked above. And I've seen my straight friends struggle with this issue as well. I just wish that people took less time worrying over and dreaming for the things they don't have and took a little more time to see the things they do have in their lives. I'm not saying to not dream of a better life. There's nothing wrong with that at all. But the thing is, you don't need more money than anyone else, the most things, or be the best looking to be happy.
Happiness begins within. There's no one else in the world like you. That makes you special. Be happy with who are and celebrate your uniqueness. Don't get me wrong, there's nothing wrong with similarities with others and with staying in shape, looking nice, or having goals. Just don't let those things become your life and have life itself pass you by.
