So sorry. You’re in good company, clearly! I try to remember that “research” is a huge, diverse category & we need all kinds to advance knowledge. Very few of us are curing cancer but we make valuable contributions. If the value isn’t clear, I take extra time to read & connect with existing work.

"read more" its also what someone else said at "the other place" and I actually think this is really good advice. Must make time to read stimulating work when I get in a rut

That includes connecting with colleagues for support - I second this suggestion!
