One of my friends texted me this morning, he had been awarded as Best Performance Salesman last year.    He thanked me " It would not happen, had you have not asked me to set goal."
I am so happy for him.
It is so important to set goals.  I believe that any achievements in life start with a thought of "I want""
A thoughts leads to an action
An action leads to a habit
A habit leads to a character
A character leads to a destiny.
There are mainly three steps of setting goal:
1.  To know what you want
It may seem easy, but many of people do not really know what they want .  They just follow their parents, teachers, and peers, to live a life to please everyone but themselves.  The true motivation is always from inside, to find what you really want is the beginning of true motivation.
2. To set SMART goal
S : Specific,  
Write down your goal as specific as possible.  It is no good to just say "I want to be a good student", First, you need to define what is good. , good grades, good social skills, good character etc, Define and focus on one area, go down to each tiny detail to define and refine what do you want.  You will not achieve your goal, if you have no clear picture what do you want to achieve.  
Specifically  "I want to improve my grades by 10 points" is much better.
M: Measurable.  
Let's be honest, don't fool around yourself.  You won't be able to achieve what you can measure.  If you want to be good in grade, academic score will be a good measure.   Your goal, no matter how big, how small should be have measurable matrix for you track.
Measurably: "I want to improve my grades by 10 points" 10 points is your measure.
A: Achievable  
What is difference between daily dream and goal?  Obviously, one is achievable, one is just as mist.  No matter how little progress/ achievement you have, it will boost your self worth and self believe, reinforce the positive behaviors which leads to form a habit.  
To break down a big goal into few steps, to mark each step as milestone for achievement, by doing so, you will have achievable goal.
Achievably: "I want to improve my grades by 10 points" is 10 points is achievable?  be honest with yourself, if not, start with 1 point.
R: Relevant
We are human beings with limited time and resources, therefore, start with something relevant to your current situation is important.  That is why the first step "To understand what you really want "is so important, as  you can focus your time and energy to your top priority.
Relevantly: "I want to improve my grades by 10 points" is relevant as I am a student etc.
T: Timebound
Without clear timeframe, it is meaningless for setting goal.  The old Chinese poem 明日歌, was just perfect to describe this point.
明日复明日,明日何其多,
我生待明日,万事成蹉跎。
世人若被明日累,
春去秋来老将至,老将至。
朝看水东流,暮看日西落,
百年明日能几何,听我明日歌。
朝看水东流,暮看日西落,
百年明日能几何,请君听我明日歌。
Timely: "I want to improve my grade by 10 points this year".
3. Plan, action plan, weekly plan, daily plan to do list
Okay,  you really know what you want and you have a SMART goal.  Now it is time for plan and action.
Make list of action plan that you need to do.  breakdown into monthly, weekly and daily.  Then stick to it.  Remember, Action leads to habit,  after stick to action plan, you will develop a habit, with good habit, you will see progress;  with progress, you will increase self confidence; such self confidence will reinforce your action, so on and so on.
It is not too late to set goal for 2021.
