To yourself - yes. It is possible to stop lying to yourself about anything, to be completely true with yourself, see the world as it is and rid yourself of all your hypocrisy, illusions and delusions about life. It is possible, but it is a very painful process to go through. This process is known by an unfortunate name “spiritual enlightenment”. This name is unfortunate, because most people picture an ascension into greatness, sainthood, or some sort of benevolence upon hearing it, but in reality, it’s just a process of stripping yourself of all the lies you’ve been telling yourself, being ultimately honest with yourself about everything, nothing else. It is a beautiful process, extremely so, profound, but it’s hard. But, as they say, nothing that’s worth anything comes easy in life. The upside is that when all lies are abandoned, there’s no more pain.

To others - no. It’s not possible, and it is not desirable. It is not hard to imagine a situation where adherence to strict truthfulness with others will bring more pain and suffering upon yourself, as well as loved ones. For example, a killer asking you where your children are. Go ahead, be truthful, you’re such a saint! That’s one of the main misconceptions about spirituality - that it’s all about making yourself appear perfect in the eyes of other people. No. The truth is, it’s all about making yourself perfect to yourself, which then necessarily makes other people perfect in your own eyes, because deep down inside we are all the same. Regardless of whether they lie or not.
