When you are young, you must have the desire to go on the road and walk with courage. It is better to face it bravely than to bear it passively; it is better to fly in the wind and rain than to stay under the eaves; excellence is the result of courage. If you are not brave, no one will be strong for you. Only those who can overcome the demons that bind themselves are truly brave. Sometimes courage is not conducive to thinking, but it is conducive to practical work. Therefore, perseverance, wisdom, humility and ordinariness are the standards of truly brave people.
