It is a common observation that the best way to success is hard work. I agree with it but having a bit of luck is not bad at all and is never extra.
In my opinion, it is necessary to work hard to own the success because only then the achievement is really yours. Moreover, working hard towards one's success enables us to acquire useful skills and to get important experience. Besides, from the moral point of view it is necessary that every person should deserve his or her success with a great effort.
In contrast, there is a view that it is much better to have an easy and continuous gain without pain. In fact, no success can ever be possible without at least a bit of good fortune. To continue, successful people are often proud that they are "lucky dogs" and moneybags, although they simple turned up in the right place at the right time.
Let me now explain why I do not agree with the previous ideas. Talking about an easy gain, I would like to recall an English proverb "Easy come, easy go", meaning that success without efforts does not last long. There is no success without luck indeed, but it is also true to say that there is no success with luck alone either. In addition, it is not luck that finds a successful person but instead successful people notice their lucky chance better than others.
In sum, having a bit of luck in life is not bad but the best way to success is hard work or rather efforts and good luck together.
