বইয়ের উৎপত্তি

লেখক তার জীবনের একটি সময় খুব হতাশার মধ্যে ছিল। এতটাই হতাশাগ্রস্ত যে তিনি আত্মহত্যা করতে চেয়েছিলেন। সৌভাগ্যবশত তিনি আত্মহত্যা করেন নি, তার আগেই তার জীবনে এক আশ্চর্যজনক ঘটনা ঘটে যায়। একদিন মধ্যরাতে তার ঘুম ভেঙে যায় এবং নিজেই নিজেকে বার বার বলতে থাকে “I can not live with myself any longer.”। এই পুনরাবৃত্তির সময় হঠাৎ তার মাথায় একটি প্রশ্ন…

I recommend you read this article before this one.

How many times did you fail to continue good habits (exercise, meditation, journaling) for more than a few days/weeks even if you are motivated? Also how many times you failed to break bad habits (browsing social media, watching funny videos, eat unhealthily, procrastination) even if you have full intentions, motivation?
