Mauvaise foi, or bad faith, occurs when we lie to ourselves in order to spare ourselves short term pain, but as a result suffer from long term psychological impoverishment. We force ourselves to believe something we arent really convinced in, because its easier.
The most common such false belief is that you dont have other options. Of course you always have other options, but find it more reassuring to say you dont. After all, its easier to sit on your ass and do nothing if you dont have options, than it is if you do.
Then at night, you feel negative ecstasy, the realization that you are capable, and you have many options, and you are the only reason for your situation. Your laziness, cowardice, and lack of motivation, and not your circumstances or ability.

Being precedes essence, lads. You are more than just your situation. You are all those things that you could become, if you only tried. Dont fail yourselves by failing to act.
