A person that can't achieve aims that he/she wants to achieve.

I agree with Shachi Chotia because who loses hope almost lose everything.
but as Bruce said it is not necessary to judge people.
we don't know alot about their situations.
and if you judge yourself as a loser you stop your journey of developing yourself.

someone who lost her/his hope in God inhoples times!

Someone who do what others want him to do. A person who hasn't got his own opinion, dreams and who give up easily.

The one who suicides.Life is a game,killing yourself means game over
