If you want to feel good about yourself... look away now.

Forbes has released its annual list of the richest celebrities under 30.

It doesn't make pretty reading. Your first reaction is 'how much?' followed by 'how young?', and finally 'why haven't I achieved that much yet?'

If you don't believe me... read on.

Top of the list is Beyonce Knowles, who made a staggering £54 million over the last 12 months - at the age of just 27.

You can tell yourself she was raised by management geniuses, and has incredible talent, but still, £54 million?

Next is Kimi Raikkonen, the racing driver, who made £27 million last year.

But hey, he's a racing driver, you have to struggle not to make millions in that job.

Then comes LeBron James, who made £25 million at the age of 24 on the basketball court.

24!

And the list doesn't get any better as you go down it:

Britney Spears (27) £21 million

And she found time to have a couple of kids and a couple of divorces.

Roger Federer (27) £20 million

And those 15 blooming Masters wins

Ronaldinho (29) £18 million
Miley Cyrus (16) £15 million
Jonas Brothers (16,19 and 21) £15 million
Daniel Radcliffe (19) £15 million
Gisele Bundchen (28) £15 million

All we can hope for is that they will get too old for the under 30s list before they start running into the 100s of millions and making us all feel beyond inadequate.

But Miley for one has another 14 years to go before she leaves this list of over-achievers, so things are just going to get more depressing for the rest of us.
