Have itchy feet.
Be up in arms.
Have one's head in the clouds.
Bang your head against a brick wall.
Shoot oneself in the foot.
Struggle unnecessarily.
Be unrealistic.
Keep a stiff upper lip
Not to show emotions
An old head on young shoulders.
Be very angry.
Get cold feet.
Behave too seriously.
Have eyes in the back of your head.
Ruin something
Know everything.
Give up your plans.
Want to travel or do something different.
