Writing tends to make people anxious, and with good reason. The first sentence of a job application letter can consign it to the bin. A speech intended to rouse can put a room to sleep. A mistimed tweet can cost you your job. And a letter to a beloved may aim to convey feelings of tenderness but end up making the recipient laugh rather than melt.

In this complete guide to persuasive writing, Sam Leith shows how to express yourself fully across any medium, and how to maximise your chances of getting your way in every situation. From work reports to Valentine cards, and from emails of condolence to tweets of complaint, Leith lays bare the secrets to successful communication, eloquence and off- and online etiquette. How do you write a job application, a thank-you card, or an email to your bank manager, to your children's headteacher, to your clients or your boss? How do you prepare a speech to win the argument, get the vote of confidence, or embarrass the bridegroom? Getting these things right - or wrong - can be life-changing.

Succinct treatments of the most general principles of style and composition, as well as examinations of specific modes of address (What is a subtweet? How do I write a moving elegy?) are accompanied by concrete and well-illustrated dos and don'ts and examples of wins and fails. Astute, sprightly and illuminating, Write to the Point will give you the skills and confidence you need to get your message across on every occasion.
