How do I modify that path that jupyter notebook uses upon startup?

I'm able to import modules in my jupyter notebook as follows:

import sys
sys.path.append('path/to/library')

But I want to edit the files that jupyter notebook runs upon startup, so that I don't have to add a path for every single library.

How do I modify the path that jupyter notebook uses?

I tried modifying PATH but that didn't seem to work. I did export PATH=path/to/library:$PATH. And then I restarted the jupyter notebook but that didn't solve it.

How do I modify the path that jupyter notebook uses when it starts?

EDIT

The libraries that I'm unable to load are not modules that I've created - they are things like numpy and scipy. I know where these libraries are in my system: numpy is at /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python and scipy for some reason is at a different location /Library/Python/2.7/site-packages. But I'm not able to import these when I boot up jupyter notebook, yet I can launch python in the terminal, and do import scipy or import numpy perfectly fine.

So, I assume that when I launch python from the terminal, it is using the correct environmental variable PATH. However, when I launch jupyter notebook it is NOT able to do import scipy or import numpy. So, I assume it is NOt using the correct environmental variable PATH.

How do I modify the latter so that it is like the former?

You could use the PYTHONPATH environment variable to set the path used to locate modules, or the PYTHONSTARTUP environment variable to run the code appending to sys.path.

You could use os.chdir.OS module in Python provides functions for interacting with the operating system. OS, comes under Python’s standard utility modules. 

import os      
os.chdir(r"path/to/library")
