Stealth requires great agility. One must be very cautious about how one approaches some creature that one should really avert. However, irresolution is for the timid. When a course has been decided upon, do it. Don't think about it. The time to be tremulous is when you have finished with the chore of avoidance.
Remember that pronouns help you a lot, replacing nouns to understand grammar tones better.
