The sign of good luck beginning is:

1: Knowing when to change people. Not afraid of opponents like wolves, but afraid of teammates like pigs;
2: Knowing when to change environments. A good environment can nurture a person; a person determines the lower limit, the environment determines the upper limit;
3: Knowing how to review. Quietness brings wisdom to life; solitude makes people clear-headed;
4: Knowing how to change oneself. Every day, make yourself learn something and gain insight.
