Two very important lessons I gained during my stay in France:
- never eat any shit they are offering you, no matter how suitable or attractive it seems. Stay true to your beliefs and moral, and reject it.
- never take anything seriously, except you own rights or the rights of another living being. Always have fun, make jokes and live relaxed but stay aware of justice and honesty.
Following those two rules, life will get a bit tougher than imagined, but after some time, some years, you will live exactly as you want: free and honorable.
