A good advice for the Way of St James
Sometimes you'll feel so fine, your bag will seem so light, you'll be in such a good mood that like Louis Armstrong you might sing "It's a wonderful world". Or you might think about Bobby Mc Ferrin...
A happy feeling, but be careful.
(wait until minute 1:07 at least)
Long distance walkers and pilgrims know the cause of such a pleasant feeling : "Endorphins are endogenous opioid peptides that function as neurotransmitters. They are produced by the pituitary gland and the hypothalamus in vertebrates during exercise, excitement, pain, consumption of spicy food, love and orgasm, and they resemble the opiates in their abilities to produce analgesia and a feeling of well-being" (Wikipedia).
Be happy, but beware, too,
otherwise your Way could become shorter
... than expected !
