I am retired, so I make sure that I behave, accordingly! Smiles.
On a serious tip, I work about 6 hours a day, Monday through Friday. On 1-2 of those days, I spend most of my time on the computer, advertising, re-tagging, listing new items(I wait until I have about 5 or 6 items), visiting forums/blogs and analyzing my business. So, that gives me about 3-4 days of finishing orders and picking-up any supplies I need. Some of my orders are huge, which means I may receive an order for 100 magnets and 100 coasters. I have to make sure I take a break and do not become "burned-out." NOPE! No way! I love what I do and want to make sure I'm still doing it, in the next 5 years.
If I were doing this full-time and wanted to put food on the table, I would have a set schedule and I would follow it! I would also stick to creating a few items and diversifying those particular items. Good luck and much joy!
