A.B.
I started my own business once when I was about 22 years old. It was a lot of work at first (paperwork, money to start, etc). Just make sure you know what you will/won't do and be CLEAR with customers. I've found that when you want to meet a customer's expectations, you need to KNOW those expectations and be on the same page. We have a couple of ladies here in town that started a housecleaning service and they do a great job. They bring their own supplies (unless you request that they use yours), they do the big cleaning jobs and leave the clutter and kids toys for their customers. They do a great job and charge a reasonable fee. I believe they do very well for themselves. They say that repeat customers are their bread and butter (they also have contracts with a couple of small businesses), but they are willing to come in and do one-time jobs (like getting ready for a party or cleaning after one) and they make separate arrangements for that (like they do pick up the toys and clear away litter and all that, but they charge a lot more). Good luck. Keep your head up.
P.S. I agree with one of the comments on here about deciding to be happy. It really has to be a conscious choice. Marriage is a struggle, but if you work TOGETHER, you will both be happy in your relationship.
