If you have an ‘M’ on your hand, congratulations! You are a unique person. 
This special mark is considered a sign of success in all areas oflife and brings good luck. People with an ‘M’ on their palm are considered to have extraordinary insight, intuition and leadership potential. They are known for their strength of character and their ability to overcome challenges.
Interestingly, the ‘M’ personality type is often associated with entrepreneurship and financial success. These people have a gift for detecting lies through their intuition. So don’t try to fool them. But there is a trick: if you are right-handed, the ‘M’ mark should appear on your left hand, and vice versa.
If the ‘M’ appears on the left hand, it means you have good luck, leadership skills and great intuition. Left-handers with the ‘M’ on the left hand are especially good at making good decisions, overcoming challenges and taking leadership. They are motivated by success and have a strong sense of duty.
But having the letter ‘M’ on both hands is considered very powerful in palmistry. It signifies great leadership ability, a balanced life and great intuition.
