Is is okay that I often laugh at how comical my life can be
Do you think laugh at anything else?
I laugh at how others can laugh on others misfortunes.
Life can be difficult sometimes but it is good to be able to laugh even when things are not going well. However you shouldn't be laughing at the misfortunes of others.
Otherwise I wouldn't feel nearly so fulfilled in life. Everyone should laugh more.
It's great that you can laugh at your own misfortunes. However instead of laughing at other people when they struggle, you should find a way to help them out. Wouldn't you appreciate a helping hand once in a while.
