While it may seem like a good idea to resign from a job and open a business, please reconsider. Running a business will chew up your time just as much, if not more, than your current job. I work from 6 am to 5 pm Monday through Friday.
Saturdays are for cooking/shopping/prep work for the week (take hubby/kids with you shopping, stop somewhere and have a quick lunch) and Sundays are my ‘relax and have fun with my Family’ days. If I am prepping food for the week, that means less time is spent cooking, and less time cleaning up after. Crockpots are my friends as they make dinner for you, essentially.
