Your first name of Jarkko is a dual influence: at times you can be extremely happy, expressive, full of fun, and good-natured; yet at other times you find congenial association impossible, being controlled by self-pity, moods, and depression. You have a sensitive nature, tuning into the thoughts of others and feeling much more than you can interpret and understand. You enjoy debating ideas and you strive always to have the last word. These contrasting qualities make it difficult for people to understand you and can lead to friction in your personal life. This unpredictable quality makes it a challenge for others to understand you; you find it hard to understand yourself. You feel and sense much more than you can fully understand, and could become psychic if you delved into the occult. It also creates a dual nature: you can be a pleasure to be around, happy, charming, thoughtful, giving, expressive, and full of fun; yet at other times, you are withdrawn and reserved, temperamental, and controlled by self pity, moods, and depression. Uncontrolled thoughts and emotional upheavals could disturb your peace of mind and upset your finely-tuned nervous system, adversely affecting your health. The problem then would be uncontrollable thoughts, feelings, and reactions. You find it difficult to be patient, practical, and systematic, preferring to act impulsively as the spirit moves you.
