To Quintin Campbell 
My dear Sir June 28. 1862
Your good mother tells me you are feeling very badly in your new situation. Allow me to assure you it is a perfect certainty that you will, very soon, feel better---quite happy---if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did. On the contrary, if you falter, and give up, you will lose the power of keeping any resolution, and will regret it all your life. Take the advice of a friend, who, though he never saw you, deeply sympathizes with you, and stick to your purpose. Sincerely your friend A. LINCOLN
