Hannah Brencher after her College degree fall into depression.
As a therapy she decided to write love-letters to strangers.
By doing this she felt better so she continued to write and decided to create a blog in which she posted all the letters she sent.
One day she made a promise on her blog :if someone asked her for a hand-written letter, she would write them one.
The day after she received lots of requests from people asking her to help them.
What is amazing is that she makes people happy.
For example, she prevented a boy from comitting a suicid.
In fact, Hannah Brencher has just one goal : to spread hapiness in the world.
In conclusion, this is a such inspirational talk for me, and it encourages me to make a difference in the world.
