Got to love the family, don`t you. always looking out for your interest advising you to do what they did.
Lisa it seems to me that if your making 10K profit after 17 months in "part-time" business you are on the right track.
If you like your business work, if it gets you motivated then what would you do with spare time?
I think if you like your part time work, keep doing what you are doing. getting a better job is always an option, even if you keep the business part time.
So what if it takes another 17 months to double your profit, if you like the work I say "just do it".
in awhile when you`re making enough I`m sure your family will be proud, and some may even ask for advice rather than offer it.
Keep the chin up, stay focused, work your plan, and have success. "you can do it"
