Don't obsess about it. Focus on the task at hand. You shouldn't be thinking about 2-3 years ahead. If you nail every homework test, semester the rest will follow. No matter how hard you work there is no guarantee you'll be a laureate. But hard work will definitely make you succeed in life and that is a victory in itself.
Failure is part of the road. You won't always get the best grade or be first. Learn to accept it. It's not whether you get knocked down, it's whether you get up.
It's a marathon not a race. Trying to do too much too quickly will only lead to burn out. Do a little each day and you'll get much further. Consistency is key. Quality over quantity always. Make sure you understand the material. Memorising without understanding won't work in your favor.
A healthy mind in a healthy body. If you want to perform at your best it is important you take care of yourself. Eat well, sleep well and make sure you are exercising 2-3 hours a week atleast.
No matter how smart you think you are there is always someone smarter than you out there who accomplished more than you at your age so don't be arrogant. Nobody likes a know it all. Respect others and always respect your teachers.
Do as much independent research as possible and practice. You are much more likely to remember notes that you made yourself in exam. If nothing you revised comes up the skill you will have developed while practicing questions is a lifesaver.
Know your basics. Grammar, verb conjugation, accents etc... It may seem trivial but such mistakes can end up costing a lot of marks if you are not careful about it.
Very interesting and very bulky. There is a lot to learn so make sure you understand everything. Practicing questions is the only way to make sure you are able to memorise all the material for exams. Practising questions will also reveal how much you understood the material and where you are lacking. Only then can you fix it.
One of the most interesting subjects with a lot of philosophical components. So make sure you ask as many questions as possible. The more discussions you have in class the better you will understand it.
Keep yourself up to date. Watch short documentaries and international news when you have free time. This will greatly help you in your essay writing.
Here is an inspiring Story that Kishun is sharing with you...
When I first got into college I was consistently among the worst ranked in my class. I even failed a semester in form 4 which was a turning point for me. I stopped messing around or caring what people thought about me and got to work. Given that my school did not have several subjects available at the time I eventually saw myself switching subjects every single year since I was in form 4 including my last year in HSC where I started a new subject despite never having done it before. Each year I would therefore be one year behind on the syllabus on at least 1 subject relative to my peers. Bottom line is no matter how badly you performed in the past, how behind you think you are or what friends/ relatives or anybody else say about you; if you are truly dedicated to your work and give it your all nobody can stop you from succeeding.
