Success and failure. A question of luck.

I'm going to tell you about two friends.
One of them is a lucky person and the other one is an unlucky person.
The first one is a person who has all the things that everybody would like to have in their life.
He has a big family with a good relationships. They are a very close family. They often meet and have a great time.
He also has also a lot of friends and he's in touch with his childhood friends.
He's having success in his working life because he's working in two companies as an engineer so he's earning a lot of money and he enjoys with his job.
He knows very well how to manage his time and he has known to used the good opportunities that the life has offered him. But the most important thing is that lucky has been with him. (He has been lucky.)
The second one is a hard working and intelligent person. He has a great talent for business. However he's an unlucky person.
He lost his parents when he was very young. This made him an unhappy person, but he knew how to manage his life in the good way and things turned out better a few years later.
He studied a lot in the university and he got good marks. Then he set up a small company. His company was working doing very well until the crisis came. In the end the company closed.
Also he got divorced and now he has some health problems.
Although he's a hard working and intelligent person, he isn't having good luck.
In conclusion, I think we have to find the success in our lives through our efforts. But on the other hand, lucky has to be on our side most of the time next to us in many moments.

Good job!

Remember that 'luck' is a noun and that 'lucky' is an adjective.
