Act Uninterested

• This technique is perhaps best known as a strategy in buying used cars. If you want something from someone and it shows, he's more likely to withhold it from you to see how far you'll go to get it. Act like you don't want it and he'll give it to you for less in exchange.
  
  

Be Exclusive

• If you want someone's time, money or attention, make her believe you don't. Make her think you're turning to someone else for help instead. She'll be more likely to push advice or help onto you if she thinks she's doing so without your permission or asking.
  
  

Invoke Jealousy

• This works best if you're pursuing a person who may have rejected you or a position you didn't get. The adage that we all want what we can't have is true, so act on it by making him jealous with another person or job. If he sees you out having fun with somebody else or succeeding doing something else, he'll be more likely to want you.
  
  

Repeat Things Back

• When someone explains her thoughts and you know she's wrong, repeat her words back to her in a different tone. Say it in a higher pitch, slower and with your eyebrows raised, as though you're asking a question. You'll make her opinion sound foolish, and she may second-guess herself.
  
  

Be Unavailable

• If you want people to value your attention more, make them work harder for it. Wait for others to call you. Make plans sparingly. Give people time to miss you. If your presence is scarce, it's more desirable.
