"Counting Days: The Mathematics of Time" by Abhay Vishwakarma is a thought-provoking guide that reimagines life through the lens of finite days. Drawing on India's average life expectancy of 70 years—equating to about 25,550 days—the book breaks down how much time is truly available after accounting for sleep, childhood, essentials, and distractions like social media and binge-watching. It reveals that only around 10,000 days remain for meaningful pursuits, urging readers to awaken to time's urgency. Divided into sections on the "time budget," the cost of distractions, and harnessing hours, it offers strategies such as time blocking, the 80/20 rule, and prioritizing health and relationships. Ultimately, this concise manifesto inspires intentional living, reminding us that time is our most precious resource—invest it wisely to shape a fulfilling future.
