Proof Of Pain

Seeing someone doing something that is impossible without going through a long phase of voluntary suffering generates respect in people.

Not in everyone, obviously, some people hate everybody who has achieved something, but in every one else who has an idea how much pain must have gone into it.

Take skateboarding as an example:

When you see someone do a trick that you know can only be the result of years of pain, you feel deep respect for that person. Only a fool would say "that was just luck".

The same is true for spiritual practices.
