climax, arrive, proceed, reach, attain, result in
至 centers on reaching a final point or extreme: arriving at a destination, proceeding to a result, or attaining a climax.
至 is an ancient pictograph of an arrow reaching the ground, symbolizing arrival or reaching a limit. The modern form retains the arrow-like upper part and the ground line below.
The top part looks like an arrow pointing downward, and the bottom line is the ground. Picture an arrow hitting its target: 至 means arriving or reaching a climax.
For シ, imagine an arrow reaching the ground with a sharp 'shee' sound as it strikes: shee -> シ, and the arrow arrives at its target.
