In a person's life, we must learn to be patient, learn to persevere, and learn to be self-disciplined.
A month of self-discipline is a test of will; a year of self-discipline is the cultivation of resilience; ten years of self-discipline, success is approaching you; a lifetime of self-discipline will surely become a winner in life.
Remember: there is no road in vain in life, and one more day of experience and persistence will also have more achievements and gains. Once self-discipline is integrated into the blood and turned into action, it may be painful at first, but the future must be very enjoyable.
