I have only a few comments to make, since my wholesale fashion accessory startup is still in infancy, and I still need the day job, basically as a tech writer. Here are my strategies:
Every time I can anticipate/plan some "no-brainer" work at the day job, I listen to a worthwhile podcast or webinar. Learn some good info this way on direct-mail campaigns, emotional intelligence, and several aspects of entrepreneurial thinking.
I try to accommodate their rushes ever-so-gracefully, so they are inclined to let me leave early for a networking event that requires drive time.
On slow days, I do online research on the clock, or during lunch breaks, and print (on recycled paper) the really relevant articles to read in "the ladies` (reading) room". Managed to locate several relatively affluent zip codes by online research, as well as good marketing info.
I keep a sample product in my car at all times, so I can show it to anyone that might have useful feedback/advice. I take several samples whenever I travel and research possible retail locations.
And, of course, I endure pointless or over-long meetings by thinking about my own business or perusing small-business course descriptions from my local Women`s Business Center.
