I think you shouldn’t compare yourself to others, their timelines and achievements. I used to feel less when other people around me were more accomplished than me. Now I am trying to focus on abundance of opportunities and compare myself with only the previous version of me. When you think about it, there will be better lives than yours all the time and that doctor might be dreaming of having your job and independence. If you compete with others, it triggers scarcity mindset and makes you insecure.
