Muriel Barbery said this quote

It's all well and good to have profound thoughts on a regular basis, but I think it's not enough. Well, I mean: I'm going to commit suicide and set the house on fire in a few months; obviously I can't assume I have time at my disposal, therefore I have to do something substantial with the little I do have. And above all, I've set myself a little challenge: if you commit suicide, you have to be sure of what you're doing and not burn the house down for nothing. So if there is something on the planet that is worth living for, I'd better not miss it, because once you're dead, it's too late for regrets, and if you die by mistake, that is really, really dumb.
