You may want to consider steering the kids into tennis. It may not be a certain route to financial security but it is trending in that direction.
Singles champions at the US Open in September each will earn a record US$1.8 million (Dh6.6m), the biggest purse in the history of the sport.
That rate of pay for two weeks' work will provoke the envy of any sportsman in the world.
The earnings of the world's best-paid footballers are usually thought to be about £150,000 per week, which works out to around $480,000 over two weeks, or barely one-fourth of what the US Open champions will make.
Kobe Bryant of the Los Angeles Lakers, the highest-paid player in the NBA, made about $25m in the previous season, which yields about $960,000 per fortnight. Gaining on the US Open, but not there yet.
Alex Rodriguez of the New York Yankees, the best-paid baseball player, comes closest to US Open money; his $32m annual pay works out to around $1.2m for two weeks. But that still is only two-thirds of Open intake.
So, master the two-hand backhand today, a millionaire tomorrow?
Sports Illustrated estimates that Roger Federer received $61m in winnings and commercial endorsements in 2010.
Certainly, hundreds of tennis players around the world are making cushy livings, but Federer money? Maybe once your child wins 66 championships and 16 grand slams.
