With the help of my friends, I actually found small jobs. Now I can work daily. Usually I work for a few hours per day (mostly from one hour to six hours per day). Currently I do not have a work contract, there is no fixed job, no fixed hours.
So currently I rather have an occasional job, but I can do it (various things) every day. This is why I call this work small jobs.
I would like to do these jobs for long term to get a better accomodation than a tent (currently I still live in a tent in the rocky semi-desert on Tenerife).
