We (wife and I) decided 2 weeks ago to go into producing learning materials, paper based and computer based, for several topics. Me appreciate making money, but have a better feeling when trying to make the world better by educating people. We will produce several smaller projects in 3 languages: German, Persian, English. We do not plan to "take over the world" with what we do, we just want to do something useful. Next week we will have the first release of an exercise book for grammar (parts of it were written some time ago, but never refined).
