The joke goes: There are 3 kinds of people

The pessimist says: Finnish is too hard for an adult to learn, mission impossible.

The realist says: With 10 years of hard work, it's doable.

The optimist says: I can do it in 5 years.

Myself I was an optimist and I kind of did it in 5 years, but it was tight. However, after having spoken it daily for 25 more years I get more and more pessimistic: There are several aspects I will not master in this life.
