Alma 21

"And they went forth whithersoever they were led by the Spirit of the Lord" (16).

We are supposed to be led by the Holy Ghost. Sometimes this can be difficult because you may not know how to recognize the Holy Ghost. I live by a rule of thumb. If it's good, do it. Moroni says:

"But behold, that which is of God inviteth and enticeth to do good continually; wherefore, every thing which invitheth and enticeth to do good, and to love God, and to serve him, is inspired of God" (Moroni 7:13).

Instead of trying to figure out if it is the Holy Ghost or not, what you should be trying to discover is if it's good or not. Anything good comes from God. The Holy Ghost helps communicate it. As you do those good things, begin to recognize it as the Holy Ghost. See the consequences of righteous action. As you become more familiar with the Holy Ghost and learn to immediately recognize it, then you will become more tuned and more easily guided.
