I don’t think hard work is enough for someone to be successful, you can work hard as you want and still end up not being successful, but their are part of countries that hard work could pay off but not in a country as African, you will need opportunities and connections for you to be successful in some certain endeavors, however in the western world you don’t need any opportunities to be successful your hard work would definitely pay off for you, there are differences in the part of the world, in terms of employment in the African what you need is opportunities and connections which can help someone become successful.
Hard work alone is not enough for people to succeed, but opportunities and environment also play a very important role. No matter how hard you work, you may not be able to express your abilities in front of everyone due to lack of suitable opportunities. Especially in the field of employment, acquaintances or connections often put others ahead of qualified people. So, not only hard work is necessary, but it is also important to get the right opportunities along with improving your skills.
I think that we should not stop our progress by waiting for opportunities. The situation will not always be in our favor, we have to create the possibility of getting good opportunities in the future by improving our skills and experience. If you work hard in the right place, you will definitely get the reward.
