Be grateful for what you have and stop complaining - it bores everybody else, does you no good and doesn't solve any problems!
Zig ZiglarYou'll never meet a happy ungrateful person, or an unhappy grateful person because gratitude and happiness go together. Sometimes happiness precedes gratitude but often gratitude precedes happiness. The latter is achieved by realising things could be worse but aren't and so feeling relieved, grateful and happy.
