Really inspiring words man. I have always noticed that the sad days doesn't last. Sorrow may endure for a while but Joy cometh in the morning. We should always condition our mind to be optimistic so we never give in to depression when the tougher days comes. We are bound to experience those days occasionally, how we react to it matters a lot.
We should always keep a smiling face no matter how difficult a situation we are currently going through. Tough times don't last but tough people do. The reason we must optimistic for better days no matter how current or present day might look like. Life can only get better
