Friends or no?

It is often said that you should surround yourself with friends who motivate you to do better and makes you wanna be the best version of myself.

I totally agree with this. But what if my friends aren't ambitious? Should I just abandon them for the greater good? I also agree that it affects me in some way or the other, there are times I don't have the will to do things which would directly or indirectly affect my career.

But these are the friends who have been by my side no matter what. They are my first point of contact every time I have an emotional problem to deal with. And that's what friends are for right?

Even though there's always an option of making new friends who have achieved something in life and are ambitious, but just the idea of changing dynamics with your existing friends is scary in itself and sounds wrong.
