What are some things that make you really sad?

The negative in everything.

Failure

It is not easy for me to be SAD,l am always jovial and full of energy.

Frustration at work

Expectations..

Abuse of others

Being tarred with the same brush due to misconceptions caused by others of my gender/culture

Negative attitude

Although I am a cheerful and an upbeat person most of the time, yet so many things make me sad: injustices, betrayals, lying, cheating, death, wars, abuse of human rights, lack of concern for others, unjustified dismissals of employees, etc. Becoming sad some of the time is part of life. Only senseful people feel sad for wrong doings and sorrowful happenings.  Of course, sadness is in degrees. Sometimes, we are mildly sad, and at others, we can be moderately to gravely sad. However, sadness should never be a permanent feeling.

Treating life as a zero sum game.

I think we all agree about one thing make all of us being that (( Failure )) in your whole life soical or work , as no one who ever is want to fail down.
