A rejection email might be a stair in a staircase you can’t see the top of yet. Keep climbing anyway.

Reading a single result as a verdict on the whole climb is understandable from where you are standing. The trouble is that the shape of a path only becomes visible afterward, and what feels like a dead end is often a step you cannot yet see above. Nobody gets to know in advance which attempt was the necessary one. You only get to keep attempting.

Give yourself the rest of the day to feel it, then send the next one. Keep a plain record of what you tried and what you learned each time. Later that record reads like a staircase rather than a pile.
