Look for the area halfway down the edge if the palm to the base of the hand.  This is called the Luna Mount. When this is well-developed, you get restless easily.  If it is overdeveloped, it shows that you have an extremely tough time staying with routine.

Another sign is with your thumb. If your thumb has a conic tip,  you are easily distracted with temptations. While you may appear quick thinking and sensitive, you're really not always as committed as you appear.

A forked end to your life line also  indicates restlessness; and the owner will be involved in activities that will reflect this.

Another way to look is in the shape of your hand.

You have square hands if you have: -Square-shape fingertips. -Fairly even spaced fingers -Square outer edge to palm. -Square base to the hand.	You have round hands if you have:  -Rounded, slightly tapered fingertips. -Middle finger is the longest. -Little finger (pinky) is low set. -Curvy outer edge of the palm. -Usually soft hands.
If you have round shaped hands, you tend to get bored easily. You like to change, make, and break relationships - sometimes without warning. You like the feeling of the chase of a new love interest. You prefer the beginning of the relationships when everything is fresh and new.
