1. Even if unable to fully follow, try sincerely

    In the beginning of Krsna consciousness, one may not fully discharge the injunctions of the Lord, but because one is not resentful of this principle and works sincerely without consideration of defeat and hopelessness, he will surely be promoted to the stage of pure Krsna consciousness.

    From Srila Prabhupada’s purport to Bg 3.32
