I didn't pass any exams at school but in my first job(this was the 1980s!!) I learnt to use a computer. and so I found that I loved working with computers and so I saved up and bought one. After a few years, I decided to start my own computer company and today a and with homes in London California. Success is all in your head you need to know exactly what you want to do in life, then nothing can stop you.
