A study just came out that showed that boys were more often dreaming to be YouTube stars (girls were looking more at STEM careers, so we’re both winning and losing here).
FWIW, my son started his own YouTube channel at about age 11 (with my support). There’s no reason he can’t start this particular dream today. It’s a great opportunity to talk about Internet safety and not using his real name, name of his school, t-shirts with his school name, etc. Can’t tell how old he is, but he definitely looks young enough that you’ll be doing the editing. Actually, my kids have been making their own videos for ages, but my son got tired of waiting for me to edit his videos, so he learned to do it himself.
