My kid plays a lot of tennis, since the age of about six or so. He enjoys it, does group practices twice a week, one private lesson and then a tournament every so often. He is age 12, but we see the commitment it takes to get to the next level and it is crazy, six days a week of practice, tournaments most weekends, travel etc. Some kids we meet truly have the drive/love of the sport and really want to do it. I'm quite happy my kid does not because the parental commitment is also intense!
