As a serial entrepreneur who has raised money a bunch of times, I have absolutely lost count of how many angels and VCs have rejected the companies I've worked for (or founded) and been a part of the process with. Now they just roll off my back. Odd though how in other areas of life, rejections seem much more personal. I suppose there is a difference between a professional rejection vs a personal one.
