More Offline Hobbies and Activities for Josh

With the coming summer vacation in six weeks time I'm now thinking of what my son will do to use some of his excess time for playing online. He's so keen on playing his favorite games online that I sometimes think he should learn to play offline games more of his time. I want him to have a well-balanced childhood and I think of cutting his online focus more on his more relevant hobbies. 

With this in mind I want him to spend his time on his music hobbies like playing keyboards and guitar. We're having an inventory of useful musical instruments for him and we're also thinking of buying a ukulele tuner just in case he wants to have his hands on that instrument. I'll have to think more activities for him online.
