there is no rush, i am not finished after 66 years.
reading math books is not a matter of finishing them, but of beginning them, and then spending some time regularly with them.
you benefit from small portions, not necessarily needing the whole thing.
just try to learn one thing. that's already a lot.
in fact i think setting as your goal to read all of euclid is somewhat pointless, and just setting yourself up for a tedious time, and quite possibly frustrating yourself.
these grandiose projects are in a way just more excuses not to get started doing something.
