Here is a short introduction of Erika Maksniemi who is our visiting expert trainer in this course.
If we have too many things to do or too difficult work, our motivation and concentration may suffer. Also studying, which is too easy, is not motivating. An optimal challenge is found to be most inspiring and thus nourishing our or our students' concentration. If external conditions make it difficult to reach, see, if you can break down your aims and tasks into the smaller aims and tasks and do some heavy prioritization.
