A good snippet to come back to whenever one needs to be humbled:

Euler's work touched upon so many fields that he is often the earliest written reference on a given matter. In an effort to avoid naming everything after Euler, some discoveries and theorems are attributed to the first person to have proved them after Euler.

There’s some of the same phenomenon going on with Gauss, as well. Not coincidentally, Gauss was probably the last person who truly understood all of mathematics, as it was known in his time.

If you think that might make you humbled, then consider that he was completely blind at the end of his life and he was still coming up with new discoveries and conversing with other mathematicians via scribes.

And raised, with limited success, 13 kids.

There should be acknowledgement that so much was initiated by his work. Perhaps via xxx-Euler's formula or something.
