If I hadn't lived in Singapore for two years,

I might not have learned which countries are part of Asean.

When I ran for president,

I asked my PM to handle various economic agreements.

I researched those matters, and as a result I became familiar with them.

That information, however, isn't something everyone needs to know.

It also isn't necessarily essential for every role.

A soldier, for example, needs to focus on combat skills rather than memorizing encyclopedic details.
