You should look at web sources that have recently been updated because a lot of times new information is present that could change the original point/evidence. This could discredit the source. You also should do this because the newer the information, the more credible it is in the time (older information could easily be outdated).

If you have more education(e.g. a PhD versus a Master degree), and a better school(e.g. Stanford vs UCSF), then you can get higher paying jobs, and a wider variety of jobs.
Hope this helps!
