1. Do it without thinking

Thick-skinned at the first level, just do it and talk later.

2. Not afraid of making mistakes

Thick-skinned at the second stage, correct mistakes and keep going. Make mistakes and correct them again.

3. Everything that happens is beneficial to me

Thick-skinned at the third stage, after all, the goddess of luck is on my side.

4. Always stay positive

Thick-skinned at the fourth stage. No internal conflict. Keep trying to get the deals that are hard to land, keep doing the things that are difficult to achieve. Making money is not shameful, benefiting oneself is not shameful, and relying on others is even less shameful.
