Write a letter to my boss that convinces them that I deserve a raise.

Hey boss, its me.  We have worked hard over these past few periods, and while I look back fondly on our memories, I have an ask of you.  You see, given how much I have sacrificed to deliver the results you have demanded over the past fiscal cycle, and we surpassed our goals, I was thinking perhaps you could show your appreciation with an reasonable increase in salary?  
Thank you for your consideration, and I look forward to surpassing our goals together in the future.
