Mr. Alex Smith (…or say a name you prefer…) is a successful businessman I know about. He is from my hometown and he now owns two groups of industries and the products line of his companies are famous in our country.

Since he is from the same town where I spent my childhood and teenage time, I have heard a lot about him and few times I met him as well.

He was a son of a successful local businessman and he inherited his father’s electronic industry many years back. That was just the starting and over time he has worked really hard and built his empire in the local business market. In few years, he took some giant leapt in his business and lately has been awarded as one of the bet business entrepreneurs in the country. From the local electronic business he had inherited from his father, he gradually and successfully amassed the fortune and business success and thus has become one of the enviable businessmen in the country.

Taking great decisions and gradually enhancing the business was his success mantra. Everyone in our locality agrees that he was an honest, hardworking and wise person who knew when to take risks and when not to. His timely decision, investment in promising sectors and hard work have rewarded him well and his industries have made the opportunity for others to earn their daily bread.
