"You" as an indefinite pronoun in a first-person statement

But like most young people of my generation, waking up 6 am in the morning to study things you do not understand, is not an idea that appeals to me

Is my usage of 'you' in this context wrong? It sounds weird, but it doesn't sound right when I replace it with 'I' and 'We' either.

EDIT: It's wrong either way right? Is it better if I replace the whole phrase with

waking up 6 am in the morning to study incomprehensible things, is not..

The you in that sentence is called a generic or impersonal you. It is very common in English and normally isn't confusing at all. It is used for statements which have no specific person but which are generally true for everyone. It's often used for proverbs or wise statements. Some examples are:

• Brushing your teeth is important
• Get to the bus stop earlier if you don't want to be late
• You don't want to miss the next episode of your favourite TV show!

The example sentence may seem odd, but it makes sense if you think of it in this way. The you in the sentence isn't really referring either to the speaker or to their listener, but is an example of a generic you. The sentence has an embedded statement inside of it. If you rephrase it this way (oh look, that was another generic you!) it will be clear how to interpret it:

"Waking up 6 am in the morning to study things you don't understand" - Like most young people of my generation that's not an idea that appeals to me

The sentence in the question is very natural and very idiomatic. Rephrasing it to avoid you will make the sentence less natural. There's no need to do that!

(But I would recommend more contractions.)
