“You cannot lift another soul until you are standing on higher ground than he is. You must be sure, if you would rescue the man, that you yourself are setting the example of what you would have him be. You cannot light a fire in another soul unless it is burning in your own soul. You teachers, the testimony that you bear, the spirit with which you teach and with which you lead, is one of the most important assets that you can have, as you help to strengthen those who need so much, wherein you have so much to give.”( Harold B. Lee, “Stand Ye in Holy Places,” Ensign, July 1973, 12) Source: http://ldsquotes.blogspot.com/2006/10/gems-teachings-stand-ye-in-holy-places.html

Having the right spirit is vital. The Lord taught:

Matthew 6:21-24

21 For where your treasure is, there will your heart be also.

22 The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.

23 But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!

24 No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon. https://www.lds.org/scriptures/nt/matt/6?lang=eng

Brigham Young further taught about this spirit and it dictates our actions or rather should dictate our actions. Enjoy.

If you feel evil, keep it to yourselves until you overcome that evil principle. This is what I call resisting the devil, and he flees from me…When you are influenced by the Spirit of holiness and purity, let your light shine; but if you are tried and tempted and buffeted by Satan, keep your thoughts to yourselves- keep your mouths closed; for speaking produces fruit, either of a good or evil character…You frequently hear brethren and sisters say that they feel so tried and tempted, and have so many cares, and are so buffeted, that they must give vent to their feelings; and they yield to the temptation, and deal out their unpleasant sensations to their families and neighbors. Make up your minds thoroughly, once and for all, that if we have trials, the Lord has suffered them to be brought upon us, and he will give us grace to bear them…But if we have light or intelligence- that which will do good, we will impart it…Let that be the determination of individual, for spirit begets spirit-likeness; feelings beget their likeness…If then we give vent to all our bad feelings and disagreeable sensations, how quickly we beget the same in others, and load each other down with our troubles, and become sunk in darkness and despair!… In all your social communication…let all the dark, discontented, murmuring, unhappy, miserable feelings- all the evil fruit of the mind, fall from the tree in silence and unnoticed; and so let it perish, without taking it up to present to your neighbors. But when you have joy and happiness, light and intelligence, truth and virtue, offer that fruit abundantly to your neighbors, and it will do them good, and so strengthen the hands of your fellow beings.
