This is significant because it shows the meaninglessness of his life in that he wants to kill himself (a serious thing) simply for a way to pass the time (a common thing). It is also important that he is unable to go through with the action, not because he doesn't want to kill himself but because he is waiting for Godot to tell him what to do.
In "Waiting for Godot," Originally written in French, by Samuel Beckett, the main characters Vladimir and Estragon contemplate leaving and staying, but under the surface, they pose questions (and possibilities) about the meaning of life, God, and death.
