I think those people are really making efforts cauz being happy in life is so hard, we always have problems there are always troubles that show up in one moment or another and it's difficult to solve them ! and it's more difficult to hide it !! and I think these people are appreciated by the others and loved so much, we like seeing persons that laugh and whom we have fun with, rather then hearing complains and watching a miserable face...So don't take life too seriously and try to keep smiling =)
