My friend is pretty well off and buys branded stuff and goes for exotic holidays. My husband doesn't earn that much and we can spend very frugally. This makes me sad and jealous. I am getting more irritable due to this reason. Help me out..

See, there's no end to comparison. Today, you are getting jealous of her tomorrow you may have a friend who is richer than her and even if you will have more money there will be no end to your jealousy. Material things are temporary. You never know, she may be going to exotic holidays, but their overall married life is on rocks. And even if they are happy and have lots of money, then also seeping the seed of jealousy would do no good to you, neither financially nor personally as a how you grow as a person. The good thing you can learn by looking at your friend is, you can learn how to manage your finances. Her husband must not be born rich, he must have worked or both of them must have worked to be this financially sound. So, you also become a smart saver. Check how you manage your finances. Make smart investments and save money for holidays as well.
