Around 2011 I wrote a number of articles for an online publication, the 99u (since folded into http://www.behance.net). The audience for the pieces were creative workers, but really they are for workers and people in general. You can find them here:
I am proud of these pieces, and I think the advice is good advice, still. Take a look when you can.
P.S. For some reason the last one is not on Behance but it is on jane.dallaway.com, hence the last link.
P.S.S. Speaking of taking a look, take a look at the art work of Oscar Ramos Orozco. He illustrated all the articles I did for the 99u, plus many more. In the background of the pieces above you can somewhat see them, but they are also distorted. To see some of the work he did for the 99u, go here. You can see his profile on Behance, here. The image above is also his.
