Dean Forbes missed out on a career as a professional footballer having once been on Crystal Palace's books, but has thrived in the business world.
The future CEO was struggling at 17 - homeless whilst also being the primary carer to his mum, who had lost her job. Forbes himself had also amassed notable debts as he attempted to keep up with his free-spending pals who had made it as footballers.
His need for an income led to him taking a job in a Motorola call centre, but 20 years of graft has seen him rise considerably up the ladder. Forbes would go on to lead a major software firm and last year, Forterro was bought out for a mammoth $1bn (£823million), taking his own net worth to around £40m.
