Why E matters
E is the single most common letter in English. Its morse is a single dot — one pulse, one time unit. Alfred Vail allegedly assigned the shortest codes to the most-used letters after visiting a print shop and counting type-case drawers.

The history of E
E descends from the Phoenician he, originally a glyph showing a person with raised arms and pronounced more like an 'h'. The Greeks reshaped it into epsilon (literally 'plain E') to distinguish it from a similar letter. Romans squared it off and English inherited it whole. E has been the most common letter in English since at least the Old English period, and is the reason scrabble tiles for E are worth only one point and shipped in quantities of twelve per set.
E in CW operating
E is the cornerstone of the entire international code: Vail and Morse made it a single dot precisely because it appears so often in printed English. Every all-dots prosign in the standard set (E, I, S, H, 5, the error sign of eight dots) sits on this foundation. Operators sometimes send a single E mid-transmission as a polite throat-clear, or a string of E's as a soft 'hello'.
What position 1 means in practice
E at position 1 means about one E for every eight characters of running English — the most common letter in the language by a wide margin. At 20 WPM you will hear an E roughly five times per second of normal prose, so E recognition has to be completely automatic before you can copy text at any meaningful speed. The Vail-Morse decision to assign E the shortest possible code (a single dot) is the single most important design choice in the international code: without it, real-text CW would be sluggish, and the entire all-dots prosign family would not exist as a useful structure.
How to drill it
E is always the first letter taught, but the trap is hearing a stray noise as a phantom E during gaps. Build the habit of waiting one full element-length before deciding whether you heard a dot — the silence is part of the letter. Drill E paired with T (a single dash) so your brain locks the dot/dash contrast at zero ambiguity.
Most-confused with: I, S, H — drill them together.
