Hanuman doesn't represent a half human half monkey . hanuman represent an energy , a 3 pronged thought process .

1. Self belief : 

The boy Hanuman became Lord Hanuman when he trusted his own abilities and strengths. He didn't believe that he could fly across the sea, towards Lanka. He took a leap of faith and a deep breath of SELF BELIEF. 

Eventually he became known as the God of STRENGTH AND PROTECTION. This story is a way of saying "Life long strength and protection arises from the seed of self confidence." 

2. Strength :

Hanumanji's divinity lies in his ever-lasting penance. He's known as the "bachelor" god or the god of abstinence (staying away from worldly pleasures like sex, alcohol, meat)

Is "abstinence" the correct way a human should live his own life? Hell no. Go have sex, drink alcohol, eat non veg, do as you please. Hanumanji's abstinence represents the highest level of determination and strength. 

If you ever feel like cutting off an evil from your life, you can withdraw inspiration from the monkey god! He is a symbol of mental strength as much as physical strength.

3. Humility :

The god of strength , one of the most powerful beings in the universe. He's also known as the greatest devotee, the greatest servant, the greatest "fanboy" that ever lived. Throughout his own existence, he served Lord Ram, the personification of God. 

Whoever you are, irrespective of whatever you've achieved, always remember to keep your feet planted firmly on the ground. The day your greatness or your success gets to your head, the Hanuman energy (the energy of strength) will LEAVE YOU. Humility before anything.
