Over the past few months, I have gotten some conflicting personal finance information from friends and colleagues. Without giving out a whole lot of personal information away, I am a US medical student who does not have to pay tuition, and receives an annual income of ~27k. aka I have no debt

I've always been pretty good with personal finance and was indoctrinated pretty young into what I think is responsible money habits (i.e. save as much as you can when you're young, compounding gains, etc. etc.). However, with my low income I am finding it difficult to save much money month to month (5-10% depending on the month). I will graduate when I am 29yo, and become a resident, where I will earn ~65k for 6 years, and finally when I am 35yo be making somewhere between 200-400k. So my main question for PF is: is it worth the extra stress and frugality to save as much as possible now, or can I just continue my small savings scheme that I have going?

The main argument that I have heard against aggressively saving now is that since our savings jump so much once we finally get jobs, there is no way for anything I save/invest now to make a dent on the savings I will be able to make in the future.

This frightens me a little bit, since I've always strongly believed in saving as young as possible. But I think it's a bit of a unique situation since unlike most professionals, rather than a slow increase in income throughout my career, I will have 1 REALLY big jump in salary in ~10yrs. But if all I can save in that time. But if after this whole training ordeal (i.e. 10yrs from now), I only have ~25k-50 saved for retirement, I think would easily be able quadruple that in a year or two at my eventual earning potential and feel like all that stressing and saving was just a waste of effort.
<bot>: I will have a large income jump over the next ten years (~27k for 4yrs -> 65k for 6yrs -> 300k). How worth my time is it to pinch pennies and start saving now?
