You're young. Don't stress about the salary now. Questions you could ask yourself are:
- Am I doing what I want to do?
- Am I contributing enough?
While you may not think it now, if you were earning 4 or 10 times what you are, you may still wonder if you have missed the bus.
My suggestion is to have a goal of what you want to be doing in terms of kind of work and skills - not only in terms of money.
Also it's important to aspire for something big. Look at what you want for yourself in terms of creating impact - money will follow.
There will generally be someone who is doing better and some not as well as you. Everyone has their own timeline, and your jump may come later and maybe far greater than others around you.
All the best!
