With all the answers such as popstar, princess and astronaut I remember I really wanted to an estate agent when I was 5... strange I know.
But, when you get older, say into secondary school, it gets harder to identify what you actually want to do. There seems to be this pressure within the education system to know exactly how you want to spend the rest of your life when you're just a teenager. It's stressful, most people just don't know and many people change their minds completely, as they should be allowed to. When you've just turned a teenager you're still developing as an individual and still have experiences ahead of you that may shape what you want to do in the future.
I'm writing this because I want to try and reassure people. The pressures from education about jobs and the future continues as you get older and into higher education and it can be worrying when you are unsure of what you want to be/do. Just remember that you don't have to decide the rest of your future right now. People change careers when they are 50 and upwards, even going to uni multiple times, so you can change your mind too! You may find you are very happy with first job you do, you may find you hate the job you thought you always wanted. Don't worry, you are allowed to alter things in your life, including your job.
Education isn't the be all and end all (even though it can seem like it when you are younger) and neither are exams or uni. We are told that our exams shape the rest of our life forever, but remember you can resit and redo things if you are not happy with your performance. If you are determined to do something, you will get their in the end, even if it takes longer than others.
I just want people to know that education, uni and jobs is not everything, or what defines you as successful which is something I think we are fed too much when we are young. Yes, they can be very important but remember to look after your physical and mental health and develop yourself as a person as well throughout your years. There are always options and you should do what you see fit to pursue happiness.
Thank you for reading this ramble haha!
