After you wake up, you will understand that you have to endure these four kinds of hardships to achieve something in life.
1.
Work hard and be kind, suffer from using your brain
Enlighten and awaken, find your direction, clarify your mission, discover your talent, set your goal, break down your goal, execute, review, and execute again
2.
Be patient and restrained, suffer from self-discipline
3.
Read and learn, suffer from loneliness
Learn according to your purpose, focus, choose what you want, leave what you want most, and delete the rest.
4.
Bear humiliation and burden, suffer from eating grass
Live a hard life for your goal, don't let the low-level diligence move yourself, feel that it is suffering but actually it is a high-level enjoyment.
When you wake up, use your results to move yourself, don't use your efforts to move yourself.
