How to get over the first step to write a letter?

The first step in writing letters is to get over the guilt of not writing. You don’t "owe" any body a letter. Letters are gifts. The burning shame you feel when you see unanswered mail makes it harder to pick up a pen and makes for a cheerless letter when you finally do. Skip sentences like "I feel bad about not writing, but I’ve been so busy," etc. Few letters are obligatory except when you need to show your appreciation. Write promptly if you want to keep your friends. Don’t worry about others, except love letters, of course.
     Keep your writing stuff in one place where you can sit down for a few minutes. Such as envelopes, stamps, address book, everything in a drawer so you can write fast when the pen is hot.
     Sit down for a few minutes with the blank sheet in front of you, and meditate on the per son you will write to, let your friends come to mind until you can almost see her or him in the room with you. Remember the last time you saw each other and how your friend looked and what you said and what perhaps was unsaid between you, and when your friends becomes real to you, start to write.
     Write the salutation--Dear You--and take deep breath and plunge in. A simple declarative sentence will do, followed by another and another and another. Tell us what you’re doing and tell it like you were talking to us. Don’t think about grammar, don’t think about style, don’t try to write dramatically, just give us your news--where did you go, who did you see, what did they say, what do you think.
