priceless advice

- Well, I must go. I hope we shall meet again. I will give you some free advice though.

- Will it cost me anything?

- What? I just said it was free!

- Yes, but my father said that free advice often turns out expensive.

- You could say this advice is priceless. Are you listening?

- Yes.

- Good. Now... if you trust in yourself...

- Yes?

- ... and believe in your dreams...

- Yes?

- ... and follow your star...

- Yes?

- ... you'll still get beaten by people who spent their time working hard and learning things and weren't so lazy. Good-bye!
