I don’t know how it is for you, but I get in different moods about my stuff. Sometimes, I can hardly bear to part with things, (especially when I’m being pressured to do it) other times I get in a ruthless mood and can easily fill boxes with stuff to donate. I’ve found it wise to sort through that box in a more sober moment to make sure I’m not tossing something that I might need. The trick would be to figure out how to put myself in that ruthless mood… I haven’t figured that one out yet.
Deadline-driven is a fact of life. It’s not good nor bad, and giving yourself deadlines can be a tool you can use to spur yourself on. Deadline-driven doesn’t make the thing any less done. Waiting to begin until close to the deadline can make the quality of our efforts suffer, that’s true, but the issue isn’t that it’s deadline driven, it’s not starting soon enough. So, yes, you can take pride in a job done and completed. And savor that relief!
