Chosen perspective drives happiness

A man I know just had his house, all 5 pets & his lifetime of archeological research, memoirs and keepsakes all destroyed in a house fire 4 weeks ago. I asked him how he could be so OK about it. He said "If I had been in the house I would have died, so I am choosing to celebrate my continued life, instead of mourning the loss of all my stuff." Our happiness really does all come down to the perspective we choose
