#1. We don't know the truth of reality, therefore, we don't know if we're ever right
As Socrates said, "All I know is that I know nothing".
We have opinions, perceptions, we see through human eyes, we make sense of the things in a human brain.
If we ever think we are "right", then we might be enlightened to think our "rightness" is based on our particular views, perceptions, beliefs, attitudes, upbringing ...
We see this in philosophy, where the philosophical "realists" contrast with the philosophical "anti-realists".
The"realists" argue that reality-is-real, that our senses and mind can find an approximation of reality, while the anti-realists argue that reality-is-not-real, reality does not exist without experience, thus, this approximation is simply a construct of the mind.
Thus, we don't know the truth of reality, and we don't know if it exists without experience.

#2. Life is journey, not a race.
When you are at a low point in your life, this is wisdom to cheer you up.
I was delayed most of my life. Called stupid. Made fun of. I always wanted to be smart like other people. I felt like a failure often.
At low points in my life, my dad said to me, "life is a journey, not a race".
