Cant write happy poems!

Ok this is really annoying me! I try writing happy poems but I honestly cant! All I can write about is sad stuff! I wrote a few love quotes and happy quotes, and they were all voted around 3 or 2 when my depression quotes normally get around 4-5 (dont mean to sound boastful or anything :P) Does anyone have any advice for me on how to write HAPPY poems?

I agree with the last person, if you feel happy then write about how you feel, If you don't feel that emotion, could you really write a heartfelt and truthful poem? Just wait till something really great has happened to you, then the happy words will easily flow.:).
