If in both hands, the mental control exercised is formidable; these are people quite prepared to sacrifice everything to win. In the left hand only, it shows people who cannot accept criticism or rejection. However, they have long memories - they never forget or forgive any slight, no matter how unintentional it may have been.

In the right hand only, it marks selfishness; people who take great pride in their achievements and who will not acknowledge help. But there is still great mental control overall all emotional life and reactions.
