This book describes techniques for improving mental abilities. Some of the things it can help you to achieve include the following:
- Depending on circumstances, use different lifestyles that improve one or another mental function.
- Experience euphoria without drugs and come up with new ideas, when needed.
- Slow down and prevent yourself from making rash, impulsive decisions, when necessary.
- Sharpen your wit, become more talkative, and entertain people.
- When necessary, lower your mood and increase emotional tension, which can reduce procrastination.
- Concentrate on reading and writing for many hours daily.
- Increase your grade point average if you are a student or improve your job productivity if you are a knowledge worker.
The proposed methods are brief cooling or heating of the body (water therapy) and three "smart diets," each suitable for a different type of task. Despite its technical content, the book is written in an accessible language and has an informative summary for each section. The book supports most of the claims in the bulleted list above with a theory and the author's personal experience (a healthy subject). Previously published scientific studies directly support about a half of these claims.
