Although thinking can occasionally bring exciting discoveries, the stages between these discoveries and discoveries are a great test of the energy and endurance of thinkers. When thinking, we don't need to tell ourselves that we are going through an exciting Process, and as long as we recognize that our actions are in accordance with the requirements of human conditions, seriously, rationally and autonomously, it is sufficient. What does the text mean? ['Thinking according to the requirements of the human condition is the mission of the thinker.', 'Thinkers must have sufficient energy and endurance to think about problems.', 'Thinkers think about problems not just in pursuit of exciting processes.', 'Thinkers must be serious, rational, and self-disciplined in thinking about problems.']
