How to be lucky?

I always felt that im an unlucky person, i dont know why i always ended up miserable. I would always give my best shot in everything that i do or i did, when it comes to job, to love. It is always the same. Sometimes im asking myself if i did something bad to others but hell no! i always respect the people around me, i always choose to do good to people, im not perfect definitely but i dont deserve any of these. I gave up everything but in the end i got nothing but pain..:( but at the end of the day, im always praying and leave it all to God. Just cry,rest and fight again!
