Many people have wondered about the meaning of life.
There are countless religions each one offering their own explanation.
Maybe it's 42? Who knows.
Whether or not you believe that you have a soul, and that your soul has a mission.
Whether or not you believe life has a meaning, why not give meaning to your life?
Is your life just to study, get a good job, get married have a family, retire and die?
Or do you want to add something else to the recipe?
Is it just any job OK for you? Or do you apply ethics when you search for a job?
Do you use the argument, "If I don't do it someone else will?" That's a great excuse to do any job.
Why not choose a job that meets your ethical principals? That would lead to real job satisfaction.
Also, people that are not happy tend to consume products just to fill the void. You can be more environmentally friendly just by being happier.
