Michael Hyatt has a brief, helpful discussion of differences in mindset between successful and unsuccessful creatives.
In biblical studies, we might not tend to self-identify as creatives. Certainly biblical scholarship involves a different kind of thing than novel writing, painting, or the like. But it definitely does require its own kind of imagination.
A few of Hyatt’s most salient points are that successful creatives “take responsibility,” “work hard,” “demonstrate grit,” and “remain humble.”
For the balance of Hyatt’s discussion, see his original post.
