My 13 year old daughter has started taking yoyo seriously in the last month. She has been practicing 2 hours on some days. She has a pretty good matrix, mach 5, braintwister to ripcord combo going already, and today she started landing plastic whip to gyroscopic flop. 8) I gave her a YYJ classic to start on, and a few days ago I gave her my G2 Nessie due to seeing her persistence and accomplishments. Definitely not pushing her so how far she takes it is up to her. Teaching her and enjoying the conversations as a result of shared interest is way better than any trick I have ever landed! 
hope you keep it up that’s about the time I started yo-yoing so he will hopefully stick with it.
