It is normal that official decisions in Europe contain information where and how to appeal the decision. This information is not a suggestion that you should appeal, it is just there for legal reasons. A new application with better plans and circumstances is probably your best option. You must convince the French officials that you are a genuine tourist and that you will leave again after visiting France.
- Make a detailed plan for your trip and calculate how much it costs. Don't forget the "little" things like a cup of coffee or an ice cream, those costs add up.
- Compare that to your monthly income after your living expenses at home.
The whole picture must look reasonable to the visa official.
