Life is a period, so you can't set your life goals beyond a certain stage, otherwise the goals will become meaningless to you. As a high school student, especially when entering the first year of high school, your goal should be set at the high school stage. It seems ambitious to set a goal of what to do in the future beyond the high school stage, but it is easy to be inconsistent with reality and make the goal lose its practical significance. Because you don't know what school you entered in the college entrance examination and what major you want to apply for. Only when your major is determined, then planning your work goals will have practical guiding significance.
No matter how you plan your goals in high school, there must be three levels: long-term goals, medium-term goals and short-term goals. Long-term goals must be ambitious, such as being admitted to an ideal university; Mid-term goals must be clear and specific, such as how many grades I want to progress to this semester. Short-term goals must be detailed and feasible, and how many points a subject wants to improve and how many points a subject wants to improve. And be sure to put goals in your daily plan. Only in this way can the goal be feasible. Otherwise, it is difficult to achieve the goal with lofty ideals, no feasible actions, or only vague goals.
