Hi Sompong,
It is a great ppt to begin a morning.
The melody in the background is lovely and has
a matching sound to the eye catchy visuals.
May I add one more thought.
It is never too late to make a good beginning,
since every day is the FIRST DAY TO THE REST OF OUR LIVES.
So no one need to feel sorry for their past behaviour.
