Sometimes, it would serve you well to accept that you're lost. Because once you accept it, you can sit back and take a long hard look at where exactly you fell off the train. And once you figure that out, you can try to get your life back on track. Or at least try and make a good attempt at it.
However, if you decide to keep going at breakneck speed without acknowledging the fact, you will crash with a resounding thud. And if you pick yourself up time and again, and keep doing the same thing, you will crash again and again.
