It's like you thought you're headed to the right direction but something crumbles and you find yourself lost. You'll make an introspect and realize that you're not really going anywhere but staying on the same ground. But these realizations make you a better person - something that you thought you wouldn't be. This happens to everyone. It's true that you make a choice, there's no turning back. But sometimes, we need to stop for a while, reflect & pick up every lesson from past mistakes and move on with our lives as better individuals.
