Being the youngest in the room means you have the most years to use what you hear. Take notes.

Inexperience feels like a disadvantage in the moment and works as an advantage over time, because everything you pick up now has decades to be applied. The people talking have already spent theirs. What they consider obvious is exactly the material that takes outsiders years to assemble alone.

Write things down during conversations rather than trusting that you will remember, and note who said what. Ask the question you are embarrassed to ask, since being young is the best cover you will ever have for it. Review the notes in a month and see what has become useful.
