@jwhamilton_ Hmm I have some ideas on how to be more productive, but regarding the guilt..

I often remind myself that this is not something unique to me, others have unproductive days as well and that gets me far.

In the end I am a professional in my profession. If I feel given task is hard, or annoying, and even if I feel I could've done it better, faster and so on, that's only because I am familiar with the task and have the skills required to comprehend it. Simply put, to understand that I haven't been as productive as I'd like to be, affirms me that I am rightfully hired to the position I am in. Next is just figuring out how to get most out of myself to keep me focused, a topic that has great deal of books written about it 👍
