Hiii !! :)
Don't hate people to easily, because love and hate has a fine line !! you can just dislike them
Angels go to heaven !! Remeber devils burn in hell 
Don't dwell in the past !! Don't dream (to much) of the future !! Concentrate on the present
Don't cry because it's over !! Smile because it happend
And most important:
If you don't fight for what you love, don't cry for what you lose !!
