When should i stop taking guitar lessons?

i'lve been taking guitar lessons for a couple of years im ok at it. but my parents want me to keep going. so my question is how long is too long for taking guitar lessons? it doesnt have to be based skills-wise. i just wanna know people's opinion on what's the average # of year you should take lessons.
i've been taking lessons for over 3 years

Take them when you feel like you don’t need them anymore, but remember, there is always something to learn.
