You are right. sometimes humans more often complain than to grateful what he got. In this case we forget that in life we have been enjoying many grace from god. then we will arrogantly boast that what is gained solely is hard work. And when hit by disaster then we try to find other people's mistake.
In our lives, we should use our time wisely and create better opportunities and hopes. Use positive work to make life better. build empaty to the others and make a good community.
