My brother-in-law has always been a tech guy since our family met him we knew that he repairs all sorts of computers, but this is just his hobby. He really never had any training from any computer school he only had developed this knowledge through constant practice. Every time he repairs computers, he always brings with him his hard drives where he stores many of his software for back up. He said it is the most important thing for him when he does something in computers. I really looked up to him because in spite of his hectic schedule he finds time to practice in computer repairs. He even taught me the basics in computer configuration. Well right now he still had his hobby, but he is more focused on his career as of the moment.
