One of the key distinctions to tell if someone is professional or not is whether they are willing to show up and do the work, immaterial of whether they feel like it or not.
There are plenty of reasons to be distracted, tired or emotional enough not to feel like doing the work but when opportunity is there to contribute, it’s good to learn to put these feelings to one side (for the time being) and commit to getting ourselves over the line.
There will of course be times and specific circumstances where it’s really important to take time out but more often than not, once we get stuck in to the creating, we can actually end up feeling better for it.
