Giving someone all your love is never an assurance that they'll love you back! Don't expect love in return; just wait for it to grow in their heart but if it doesn't, be content it grew in yours. It takes only a minute to get a crush on someone, an hour to like someone, and a day to love someone, but it takes a lifetime to forget someone.
Don't go for looks; they can deceive. Don't go for wealth; even that fades away. Go for someone who makes you smile because it takes only a smile to make a dark day seem bright. Find the one that makes your heart smile.
