Advantages of mules
Mules, having hybrid vigor, can grow taller than both parents. Weight for weight they are stronger than horses, and are much longer-lived with much longer working lives, although maturing slightly later. They rarely become ill or lame or suffer wounds, can withstand extremes of temperature, can live on frugal rations, have tremendous stamina and resilience and are exceptionally sure-footed.

 Mules' temperament
Mules have a reputation for being obstinate and bad-tempered, but as with donkeys, the mule's legendary stubbornness is in fact a manifestation of its talent for self-preservation. There are times when a human finds this 'talent' annoying, when he is disobeyed by a mule, but there are many other times when it can be a great advantage: if a mule takes care of itself, then it follows that it is also taking great care of its cargo, human or otherwise. It is not for nothing that mules are chosen rather than horses to take tourists down the Grand Canyon! By intelligent handling, it is quite possible to foresee occasions on which a mule is likely to be 'stubborn' and to avoid them.
The undeserved reputation for bad temper is, I believe, due to the mule's unexpectedly sensitive and non-trusting nature. Until he has learned to trust a person, he is worried that the person may do him harm, and will take defensive action (never offensive) by kicking them, should he feel the occasion merits it. And mules are splendid kickers - they kick fast and accurately, and if a mule misses, it is because he intended to. Unfortunately many of the people who have worked with mules over the centuries have not appreciated this sensitivity, and have not understood another characteristic of the mule: that you cannot force him to do anything, but must persuade him, or organize his work so that he is only asked to do those things which he will want to do. Failure to appreciate this has led to many a battle between man and mule, and to the mule's bad reputation.

 Mules are highly intelligent - mule devotees would say more intelligent than horses - and are very quick to learn, with a grasp of a situation which often seems little short of miraculous. This means that their handlers need to be quick-witted to stay one jump ahead of them. A well-trained and handled mule is obliging, kind, patient, persevering, calm, tolerant, sensible, loyal, affectionate, playful - and also proud, jealous and calculating. Being so intelligent, a badly trained and handled mule can be a problem.

ARE MULES DIFFICULT TO LOOK AFTER?
They are very easy to look after in that they are rarely ill or lame, rarely need shoeing, are not fussy about their food and can withstand extremes of climate.

ARE MULES DIFFICULT TO TRAIN?
No, but their natures are different to horses';.you must gain your mule's trust and learn to understand each other, and then he will do anything for you.

 The Well

A parable is told of a farmer who owned an old mule. The mule fell into the farmer's well. The farmer heard the mule 'braying' -- or -- whatever mules do when they fall into wells. After carefully assessing the situation, the farmer sympathized with the mule, but decided that neither the mule nor the well was worth the trouble of saving. Instead, he called his neighbors together and told them what had happened...and enlisted them to help haul dirt to bury the old mule in the well and put him out of his misery.

 Initially, the old mule was hysterical! But as the farmer and his neighbors continued shoveling and the dirt hit his back...a thought struck him. It suddenly dawned on him that every time a shovel load of dirt landed on his back...HE SHOULD SHAKE IT OFF AND STEP UP! This he did, blow after blow. "Shake it off and step up...shake it off and step up...shake it off and step up!" he repeated to encourage himself. No matter how painful the blows, or distressing the situation seemed the old mule fought "panic" and just kept right on SHAKING IT OFF AND STEPPING UP!

 You're right! It wasn't long before the old mule, battered and exhausted, STEPPED TRIUMPHANTLY OVER THE WALL OF THAT WELL! What seemed like it would bury him, actually blessed him...all because of the manner in which he handled his adversity.

THAT'S LIFE! If we face our problems and respond to them positively, and refuse to give in to panic, bitterness, or self-pity...the adversities that come along to bury us usually have the potential to benefit and bless us!
