• Show genuine interest. 
  Let them know you care. Express genuine interest by asking questions. Get them talking. I find the act of talking and thinking about something you are genuinely interested in and having someone stoked to hear about it is one of the best feelings in the world.
• Acknowledge what’s important to them. 
  When you acknowledge what’s important to others, you provide a form of affirmation and validation about who they are and what they’re doing. Whether they can admit it or not, everyone craves this acknowledgement. The affirmation and validation of this is an amazing confidence and self-esteem booster.
• Say “Well done”.
   Let people know they’ve done a good job when they have! Nothing worth doing is ever easy. Worthwhile things always takes time and effort. One good way of providing encouragement to your friend is simply by saying “Well done” or “Congratulations”. These words can sometimes make all the difference between “keep going” and “give up”.
• SAY “THANK YOU”!!!
  Common courtesy!!! Good manners. It’s only natural to expect a reward after hard work. It’s only natural to thank someone when they do something for you. Say thankyou to someone right now. Thank your girlfriend after that surprise breakfast in bed she made you. Thank your friend for lending you that Simpsons DVD. Thank the producers of Arrested Development for FINALLY deciding to make a movie. A simple thank you lets others know what they have done is worthwhile and meaningful to you.
• RECIPROCATE THE FAVOUR! 
  If someone does something nice for you, show your appreciation and simply reciprocate the favour. Think of it as a pendulum. They do something nice for you. You do something nice for them. They do something nice for you.. Etc etc..
• Ask for advice or confide in your friends. 
  This is almost like flattery. Haven’t you felt like you were on top of the world when someone asked you for advice or confided in you about something personal or important to them? Didn’t that make you want to help and do everything you can to ensure their faith in you is well founded??
• Offer to lend a hand! 
  Waiting for someone to ask you for advice is passive. You can be proactive and a sick cunt by offering to lend a hand. If that person sees that you are willing to commit your own time and energy in their interests, they will be more committed to seeing it through and less likely to give up themselves.

I love that the whole time I was reading this all I could think of was my best friend and how he is the only one who literally does ALL of the above.
