I think you need a vacation! Perish such thoughts - don't leave work! Apart from kids and home - you need to save for your retirement and also be healthy. At one point, my husband's business was doing well and I too went through this phase of giving up my job and just enjoy. But I continued - with less determination though. When his business hit a plateau - I was glad I had my job. If you feel stressed or bored, it is time for a nice long vacation - you need to spend on a holiday if you cant afford it. You can just chill at home for 2 weeks or so. Hope this helps!
