There are only two mistakes one can make along the road to truth; not going all the way, and not starting.

The two mistakes sit at opposite ends of the same road. Never starting is the easier one to spot, because the question simply stays unasked. Stopping partway is harder to see, since a half-understanding arrives with confidence attached and can pass for the whole answer.

Think of something you once began to look into honestly, about a situation, a relationship or yourself, and set aside when the answer started to become uncomfortable. Ask what the next step towards the truth of it would be. It can be small, and you can choose when to take it.
