Used to think digital was the only way to go. Seeing a hand-drawn section just makes the whole stratigraphy click in a way a photo doesn't. Changed my whole view on field recording.

That "not being afraid to ask" part is key. What was the hardest thing for you to finally just post a question about? I bet that one felt the best to get an answer for.

Totally agree with the softer approach first. I always send a "friendly reminder" email before anything else, like maybe the invoice got lost in their inbox. Attach the invoice again, keep the tone professional but chill, and set that clear deadline. It saves the working relationship and honestly, most people just forget or have a cash flow hiccup. Going nuclear right away burns bridges for no reason.
