Wow this is definitely so true , it's true that there are many things in our life's that keep us so sad and miserable, but no matter how sad u might be it's not like the "thing or person" who is doing that is going to care at all, so why bother, rather than being prisoner and chained by that restraints, its more better to just try to not let things bother u! Even if it's really hard , practice take it with a smile and handle things in a calmer happier situation will make life much more free and joyful. :-)
