I wish that as a teenager I had better understood how to discern the will of the Lord for me. Over the years I developed a phobia of making "wrong" choices or "mistakes," so I made decisions by default, leaving things to chance, or asking someone else rather than actively seeking the will of the Lord in my life. The Lord, however, expects us to act.
Here are some scriptures I have found that have helped me to understand that I am free to choose, and how to best use that freedom.
Alma 37:37: "Counsel with the Lord in all thy doings, and he will direct thee for good."
Jacob 4:10: "Seek not to counsel the Lord, but to take counsel from his hand."
D&C 58:26–28: Agency endows us with the freedom to develop our capacity to make wise choices.
