Readers are always interested in learning a bit about the author of a book they are reading.
Here are some tips:
1) Your bio must be short (3-4 sentences)
2) Your bio should try to capture a tone similar to your book's tone. If the book is funny, the bio might be humorous. If it's inspirational, you might highlight something about yourself in that light.
3) Your bio MIGHT include the following:
Your age, residence, hobbies/interests, key experience (related to book), future goals.
