Thank you for answering my question.
If you don't have the guts to kill yourself, then you value your life. And the only way you could have valued your life is through introspection, whether consciously or subconsciously. Since you arrived at the belief that you couldn't abandon your mortal shell for the void, there was some period of time (however brief or unconsciously) you reflected on life. Thus, it's good to analyze your own life. Nobody else can do it for you and nobody else will decide for you, because you're stuck with the choice.
By the way a good reason for living is also a good reason for dying.
