Small Thought.   Whatever is your religion, you should not try, neither to
understand what is happening in your life, nor to seek to understand the because.
There is no explanation.
However, maybe the only possible interpretation is due to the fact that
you have been chosen to assume and to accomplish difficult task.
You should consider it as a privilege, accept it and embrace it gracefully.
People give nothing for nothing is a selfish saying.
On the contrary, you should give generously. happily, love, care without
expecting something in return.
Most importantly, you should never give up on people who are unlucky,
helpless and trapped in a downward spiral. 
Help them and you will be rewarded by the providence.   Viva
