There is no try? Sure?

Nephi says, in 1 Nephi 17:15, that:

Wherefore, I, Nephi, did strive to keep the commandments of the Lord, and I did exhort my brethren to faithfulness and diligence.

I will go and do... do, or do not, there is no TRY! Yet, Elder Holland says that we are blessed just for trying--kind of like how 'desiring' is the first step of Faith (Alma 32), and Nephi just said that he strove to keep the commandments; if we can only just desire, we will be blessed and out of that desire can come miracles (through faith...).
