My dad always told me a story of three brothers, whose parents tested with life questionnaires and here is the question; how many times will a thing happen to you before you learn your lesson?
First person responded, 4 times the third time I will definitely learn my lesson.
Second person said; 3 times and he would learn his lesson at that point and lastly.

The third person said; "it doesn't have to happen to me before I learn my lesson, instead I will learn from when it happens to my brother's."

This is a very important lesson in my life and I hope some one here gets the key message, you must not learn your lesson through your personal experience, those stories you read in news, social media concerning your bitcoin or crypto custody is enough for you to learn.
