What it's Happiness?
Happiness it's a road not a destiny, doesn't need any external factors.
It depends on you!
That's why you need to work like you don't need money.
Love like if you don't know what's been hurt.
Smile like if you don't know what's sadness.
If what it's happening to you right now it's pain, suffer or loneliness, the only thing you can do it's to be aware of the situation.
You can always learn from mistakes, you can always learn how to love yourself you can always learn from suffering, in positive ways. You need to wake up and be Aware of your surroundings.
Remember life it's to short, you can learn the Road of Happiness.
