When you're working from home it's important to remember that your actions and results count more than ever

Unfortunately, in the office, many tend to think that your punctuality is the largest factor in how hard you work, meaning if come early and stay late you're a hard worker.

This is true to an extent. If you're goofing off or procrastinating during the workday, staying late may be exactly what you need to do.
What we see, naturally, turns into what we think. If everyone saw Paul come in at 7:45 am and stay past 8:45 pm, it must mean Paul is working a ton and being awesome.

When you work from home, no one sees you roll into the office, and is calculating your daily activities. Consider this as a type of liberation. It’s time for your colleagues to recognize you for what you accomplish, not how impressively short your lunch break is.
