i am confused in my future i like to become a police officer or doctorate

Hello,
Whilst it is good that you have a few ideas what you would like to do in the future no one can tell you which career is the best for you as you are the only person who knows what will suit you. As you are stuck between two career paths there are a few options which will help you to come to a decision. My advice would be to contact people in each field that you could talk to about the career or even shadow a day of their lives in that career. You could also get involved in some volunteering/work experience and see what each career really involves as there are often many different aspects to being a police officer or doctor or any career than you realise and many different roles and specialisms within the career.
To go into a career in such social fields it will be useful to gain some experience as this will portray enthusiasm and interest and also show that you have relevant skills.
If you need anymore advice just let me know but don't be afraid to use career services for their advice too!
