How does “good luck” affect our daily life?
It's hard to confirm that luck really exists. However it's obvious that nobody wants to be unlucky. Therefore, we do all kinds of stuff to make ourselves luckier. Some believes in astrology, others are fascinated in fengshui or crystal power. As proof, our English teacher once took dozens of pictures, they were quite similar: a student with a big smile was touching the foot of the bronze statue of John Harvard. Believe it or not, they were all taken for the same reason. “It may bring good luck.”
My topic here is not about the existence of luck, or the philosophy of luck. In fact, let’s ignore those big, profound questions and ask something simple, what will happen if I believe something I did would make myself luckier? Will it change anything if I just believe I’m lucky?
In general, I don't believe in this kind of superstition stuff, and I find them both meaningless and a waste of time. But since quite a lot people actually believe in them, I did a research about how “good luck” affects our daily life.
The result was a little beyond my expectation. Superstition didn't turn out to be completely negative. In fact, just like every coin has its other side, “good luck” somehow has positive effect.
First and foremost, a belief in luck helps our mind to build up an illusion, or should we say, a magical anchor. It significantly stimulates our confidence and creativity, which may lead to a surprisingly successful performance. This kind of effect can work in all sorts of self-directed tasks. In short, believing in one’s own good luck can be pretty useful and convenient.
Following that, lucky charm also has possibility to bring an optimistic attitude. We believe that we are blessed, simultaneously; we find our life more hopeful and smooth going. Undeniably, tiny things can easily affect subject feeling, lucky charm is apparently one of those tiny.
Afterwards, “good luck” has some other enjoyable effect. Keeping being rational can be dull sometimes; we all need space and time to do useless but interesting or entertaining stuff. To conclude, chasing “good luck” could be an excuse to escape from the rational and well-ordered world for a little while.
Yet meanwhile, just like a magical spell can’t create the whole world, “lucky charms” can't fix every problem.
To begin with, “good luck” can’t help you win a lottery. (Remember that here “good luck” means the belief “I am lucky”) Pretty ironic, huh, but it is the truth. When random factor becomes the determinate of an incident, “good luck” serves no use.
The same thing happens when facing a problem that requires extensive experience or a mastery of skills. The reason seems to be obvious: “good luck” only helps when the problem can be mentally or subjectively affected.
At the same time, “good luck” may have a negative impact on the way people conduct their lives. When you overdo it, or to say apply it to the extreme, this little belief or ritual become a superstition. There is no doubt that it will ruin your routine life, interfere you clarity, limit your mind and creativity. To make things worse, superstition is a virus that can be passed by people to people, generation to generation.
All in all, “good luck” is the sword that cuts the both sides of an issue. Don’t belittle the advantages it might bring, and simultaneously don’t cocoon in it for it could be a waste of time or a monster beyond your control.
