Thank you @jessicakluthe for the thoughtful response! I love my current networking groups, but the travel time and preparation can be overwhelming. I think if I pack all meetings into one day, I'll be much better off.
I'd rather have an 8-hour day of meetings than two days of 3 hour meetings... sounds crazy, but I have difficulty regaining focus after being out and about ;) And - what I wouldn't do for a sound-proof office!!!
Like most things in life, it's best to diversify, and I've routinely done the opposite. Moving forward, though, I'm striving to do enough of everything. Balance!
