Remote workers listening.. How do you monetize your knowledge?

Hi HN people, I'm a 30 guy from ol' Europe (sry for my English) and I'd like to share my story, If You have a suggestion for me please leave a comment below! I've a CS degree and I consider myself a Web Developer even if It isn't the main job which "pays me the bills" :D

I like comparing, experimenting, blogging, developing with new cool tecnologies, often I share the code on GitHub, sometimes I build a Side-project,.. but It isn't a job. When I'm not at the computer, I like to sleep, walk, run, swim, travel, attending at conferences,..

I tried to be a regular worker but I wasn't satified:

- Small company, web developer. Write code like a monkey before requirements, sleep nights at work,..

- Very big company, everything consultant. They didn't know the techlogy. Man in the Middle to Indian developers, my work was just to check and test the others progress.

- Startup Buzz. I didn't work there, but many Steve Jobs wannabe wanted a working prototype from me. :D

- Freelance. I'm also a freelance, I teach at courses, I'm a remote consultant (200€ a day) but many customers are a waste of time and some of them don't even pay you here. Unfortunatly I can't move to London or Berlin (I receive a lot of job offers from there)

So how do I earn money? Ehm.. I'm an AdSenser. I've a not so great site which I'm not proud of it which pays the bills for me via AdSense. I do 25k € per year, it isn't much but It's enough for my lifestyle.

Are you in a similar situation? I'd like to reach 35k €, working maximum one week per month (via consulting) and the rest monetizing via AdSense and Side-projects, do you have some suggestions to differentiate my business?

Thanks Luca
