Many people work remotely. Not so many are productive while doing so. You need to focus on the things that have the biggest impact each day. And you need to build yourself a daily structure/routine that works for you - and stick to it.
A key element of success at stanwood is setting ourselves high goals each year. At the end of the year, we do a resume to see what we achieved and especially where we failed. We do this on a company level, team level, and also on a personal level.
For the longest time of my life, I set myself SMART goals.
