What Does This Mean?

I heard this line in a song once, and i know it is a piece of symbolism, but dont really know what it means, what are your suggestions?

"You can run a thousand miles
But you cant swim and inch up the Nile"

thanks

you are good at running but you've never learned to swim?

i suppose that is a possibility, does anyone else have any other suggestions?

If you're good at one aspect of life it doesn't mean you're any good at anything else.

Maybe the current in The Nile is really strong? Maybe it's full of mud or crocodiles?

Dear Old Cheesey, he always tries to work a EATB reference into his answers!

Who? Me?

Yeah you! I don't think the young un's twigged though.

I'm sure I don't know what you mean, it's not as if I never stop or anything, y'know.

Do you still live in Villiers terrace?

Nah, we had to move cos the neighbours kept chucking rubbish over the wall.

It was a pleasure Dr Cheese, you'll have to forgive me I'm having one of my turqoise days.

I know all about that syndrome, I read it in books.

you two

For what it's worth, I think it means that no one is perfect. Mostly what Botley said, too. Someone might be so full of themself about how good they are at one thing, and then be so horrible at another. Sometimes the people you think have it made, really don't. It'd be streching it, but I almost see that as something like having skeletons in your closet.

Btw, what song did you hear that in?
