This is a huge question/issue for home business starters. Even running your own business can leave you feeling less secure than you prefer. I`ve only been a Virtual Assistant for 7 months and I made the huge mistake of putting all my eggs in one basket, or all time with one client as it were.
I quickly found that this was a bad practice because now this one client is gone and I am left with no income. I am fortunate because my husband`s "day job" pays the bills but if I had been reliant on this income I`d be in a world of hurt right now.
The best advice I can offer is not to rely on income from a home based business until it is well established and ALWAYS have a plan B to replace income that is lost along the way.
