Just stating you've matured isn't very useful.

Matured in favor of, or in opposition to, or in a different path altogether?

How do you plan to spread that maturity to others if what you're sharing is not clear? I grew up on the same diet of SF authors, and while I do acknowledge the need for work to be done here on earth, we shouldn't let that need tear down progress towards space. Especially when space expenditures are such a small part of what we as a country and the world spend our resources on.
