Inevitabilities are going to happen regardless of what we do in life. The goal of this book is to develop tolerance so we can charge through these difficulties. Building tolerance can be a push-pull. Many inevitabilities create uncomfortable feelings like anger, fear, sadness, depression, regret, and jealousy. As a result, we pull away from them because experiencing these emotions can be quite challenging. In doing that, situations can get worse, not better. By pushing through we begin to feel comfortable even while feeling uncomfortable. This book first helps to understand the struggle of life and then to build tolerance by integrating the tools provided to help learn, combat, and lean into challenges.
