Hi Daniela! I think inspiration for the medical field can come from many sources, sometimes acting together and sometimes just one that's enough. For me it was my grandmother's illness, she had dementia and it exposed me to care and the academics of medicine. After I kept pursuing the dream, I like to volunteer in the ER and help patients, I love to study and even became a tutor in the sciences and I did a little research and shadowing as well. I think it begins with an inspiration but then dedication and hard work build resilience in pursuing your dreams even when facing obstacles. Think about what makes you like science and medicine; maybe a volunteer opportunity or an anatomy lab or a more personal experience. Whatever it is, let it speak to you and be honest about it, remember it's not a clear cut path and can have many differences between prospective doctors!
Best of luck!
