Traditional answer :
A loser is a person who lost something; a game, a compitition, someone etc. A winner is the one who won what a loser lost.
A loser looks down to himself in most cases, feels angry and thinks he must win in another time to have a value.
No one wants to be a loser.
But, look at it from another angle.
You lost, so you learned there is something you did that was wrong, then you learned a new thing, then you've won something that the other winner didn't win. Strange viewpoint, and I am almost sure it didn't convince you.
Ok, let's change the viewpoint even more. If you lost something, then you have less ways of losing it again! :D. Clarifying that, let's say that there is n ways you could lose a runnig race, you don't know all of them yet, so you aren't prepared for each one. So one of these ways have made you lose. The next time you know that way, so you are prepared for it, so you now have n-1 ways of losing ;). One after another, you'll eventually have zero ways of losing.
The inventor of the electrical light bulb, Thomas Addison, who performedthousands of experiments until achieving the desired result. "Who here has made that many attempts to succeed in something? Do we try more than two or three times before we give up?", "there is no such thing as 'I can't do it', there is 'I can't do it yet, and I have to keep trying'".
So personally I see each failure as a step towards success. Perhaps programming have tought me so, fixing an error after anothet till the compiler is shy from saying another error cuz keda 7aykoon beystahbel :D.
A real loser is the one who don't learn from his failures. And a real winner is the one who keeps learning till he reaches. A real loser is the person who stops trying. And a real winner is the person who never stops.
One last word, A real winner of winners, is the person who is not satisfied with the desired result after he achieves it and keeps trying to improve it further and further till he makes the best result in the history and possibly for several centuries to come. That is a real scientist mind.
So, people who read this post, if you have failed in something, don't get stuck at that and keep crying about it forever, get over it and just try another way. It is the same concept as lighting a little candle is better than damning the darkness thousand times. Don't be just optimistic, believe in your capability to do it and foresee the expected ways of failure to decrease the times you have to try.
A side note, there is a group (osra) in our college, that had failed many times, but personally, I never gave up on it; believing that as we keep trying we sure will reach isA. Even if we just reached experience of how to avoid such failures again, that would be enough. But what did I say above ? If you actually reached that, there is nothing called 'enough'.
keep in mind
