Bad life is people are just under-exposed to bad potential. They haven't even exposed their potential even to the barest minimum.
The skills they are still here to learn,
the places they are still here to explore and the challenges they are still here to face makes life so boring to them. They don't know what to achieve. They feel as if they are already a failure while they have not even made that move to express their potential.
Most people are just under-exposed to their own potential. They just want to play safe every time and expect a big result from nowhere which is not true so you need to explore life and understand the challenges that is within because until you unlock your full potential.
You can never be fulfilled in life you need to achieve a lot you need to work on things believe yourself and always be the best at what you do for that you can find fulfillment in yourself and in life.
