How can I write better?

Answer: Follow William Strunk’s excellent advice in The Elements of Style.

Over 10 million copies  of The Elements of Style have been sold in its various editions. The 1918 original edition was a slim 45-page book written in William Strunk’s delightfully dogmatic style.  It hasn’t been out of print since.

Here’s the pdf version of the original 1918 version. Print it off and study Strunk’s wise advice. Maybe some of his advice on word usage is now out of date, but it’s still a remarkable collection of writing wisdom that is just a click away:

Or, better still,  buy the latest version: the 105-page, 1999 fourth edition of The Elements of Style by William Strunk Jr. and E.B White.
