If you could take a pill that meant that you could never fail, would you?
No. If you always succeed than you have nothing to compare the feeling of success to. It becomes like any other normal task that is carried out with no thought or consideration, like, I guess you could say breathing. Because all of us grow up breathing every minute of everyday (otherwise we die) we have nothing to compare that feeling breathing to, so the emotions we feel when breathing feel like nothing because they are constantly there.
Similarly if you win all the time then the emotions associated with it become the norm, and meaningless. Never failing ensures each goal you set yourself is not really a goal because it can be achieved without thinking. Do we get any satisfaction out of no effort? I certainly don't and to me if I don't get any satisfaction out of a task I have attempted, regardless of whether I have done well or not, I have failed.
So what I am trying to say is by never failing, you always fail.
Never failing sounds great and it probably is for those who simply don't fail naturally. However, having an unfair, manually administered advantage (such as a 'failure-be-gone' pill) seems like cheating. Personally, I don't think I'd be able to sleep at night, knowing I'd voluntarily cheated on an exam and had therefore beaten others who had studied and worked hard in order to achieve their results. Also, failing can give people a sense of direction in their lives and can help them determine what they'd like to do in, and get out of, life. In spite of the cliché, failure can be character-building and is often an amusing topic of conversation; people are often attracted to those who have faults, rather than a Mr/Mrs Perfect who they are likely to feel intimidated by. In conclusion, while at the time seeming like a hindrance, failure can have many benefits and can help build up a stronger, more interesting personality.
Definitely no, to take such a pill would take away all the excitement from life.
As soon as the chance of failure is taken from a situation what reward can you possible get from it and if you succeed in everything you will never appreciate victory as much than if you failed the majority of the time.
But perhaps more importantly than enjoyment you would never learn anything if you could never fail, you would only gain knowledge that is immediately relevant to succeeding meaning you would never be able to become wise or intelligent.
Interestingly though what would happen if two people who had taken this pills had a fight, would it last forever? Would two pills negate each other would the person who took it more recently win?
If the last is true then generals would require no tactical knowledge to win a war just popping a pill every few hours (depending on whether the pill wears of or not over time).
Overall if believe that if I took the pill I would miss out on many of the wonderful things in life and if the pill was available to everyone then the world would descend into madness or monotonous victory depending on whether people could still clash if both were assured victory.
