Anyone earning their salary from home? Need tips!

I caught myself searching on the web for an part time job, working from home. An there´s a lot of scams out there. It doesn´t seem to be any way to work from home. Other than those survey-this, and other stuff you have to pay for first, in order to get something to work with.. It doesn´t seem legal, do you think?

I work as a porture now at the hospital. And the most of the time, I walk. Been doing this for the past 3 years now, and I can begin to feel my legs pulsing, like in having some nerves itching. We do get some really good shoes from work (hoka one one, it´s like walking on waves), but still, I can´t do this for the rest of my life..

Does anyone have any recommendations? Any ideas for a part time, or full time job, working from home?
