It is exceedingly difficult to find truth. Truth can be obvious, but is usually elusive and required persistence. It’s a needle in a haystack of bullshit.
Easier: perceive and discard lies. Bullshit usually stinks. Truth gleams brightly in the light. Use your sense of smell to reject bullshit.
Especially watch for bullshit artists. Trees and fruit. By their fruit shall you know them.
Bullshit artists are a never ending fountain of more and more lies. Get rid of the source.
Like attracts like.
Or, another way to look at it: don’t be dumb. Don’t be clever, just don’t be stupid.
Don’t seek your passion. Stop doing things you hate instead.
And if you can’t figure it out, be agnostic.
