Soul does not like excited state rather it likes state of equilibrium which can be attained by happiness only.
Life is a composite state for soul and it works on the basis of alternate theory like:
Day after Night
Dark after Light
Thorns after Flowers
Hunger after satiation
Fire after smoke
Universe has coiled itself in anticlockwise pattern and life is opening itself in clockwise pattern.
Want to be happy in every state of life, just tune yourself with it and be happy.
