The more you face someone at a higher level than yourself, the more you should be sincere and simple.

Because they have played the same tricks you have, and they have also played what you haven't, they can see through all your disguises in one glance.
Although their attitude towards you may not change much, they have already blacklisted you in their heart.
Some people like to boast about their strength everywhere; ultimately, it's still a sign of insecurity, afraid of being looked down upon by others.
In reality, sincerity has its own tremendous power. Everyone starts as a beginner; there's no need to pretend to be something you're not. When your abilities and desires are aligned, you can truly be confident and humble at the same time.
