Big impact Quote by Timothy O'Donnell
“Technology has also had a big impact, especially on the bike. Now everything is tested aerodynamically, wind tunnels are used to optimize performance, and frames, wheels, water bottles are all tested. Even clothing, like my Castelli Stealth Top, is faster than skin.”
![“The best writing advice I had was [in] ‘Heinlein’s Rules for Writers’ by (American science fiction author) Robert A. Heinlein. His first rule is that you must write, and I was already doing that, but his second rule is, ‘You must finish what you write,’ and that had a big impact on me.” quote by George R. R.
