If your job allows it, work remotely using communication tools, coming to the office only once a week

If your job permits, arrange to work from home using communication tools (and conference programs), coming to the office only once a week, let's say on Mondays. You'll save both money and time on fuel every day, as well as money spent on lunch. Lunches need to be prepared in evenings - just heat them up in the microwave during the day. You need to always be online at home and work as efficiently as you do in the office, allocating your time for better results as you see fit. You need bonus systems and to set them up if you like and if the job isn't burdensome, if you want to work until 23 hour, with a variable salary based on tasks. For example, an accountant is paid for the number of reports, or a lawyer for prepared documents. This is also applicable to a 4-day workweek. If your job allows it, arrange and accept remote work for yourself.
