The ancients said "standing at the age of 30", in fact, it should be done by the age of 30. Because of medical conditions, the life span of the ancients was relatively short. By the age of 30, life is basically over half. At this time, they should have independent ability to support their families and children.
In today's society, the so-called 30-year-old should actually be 30 years old. He has his own career and is willing to work hard for it. Have their own family, willing to make sacrifices for the family; Have friends who care about each other and are willing to make concessions for each other.
I think what we are talking about now is a state of mind. When you reach the age of 30, you must have the ability to face this society independently and have enough anti-attack ability, because you are old and young, you must persist and work hard to make them live a happy life.
When we are 30 years old, we must have a clear goal and the direction of struggle, both in our career and life, and we are moving towards this goal and direction.
Most of us can't seem to reach this state now, which is also the goal we should learn and should constantly motivate ourselves for this state.
