I don't want you to think that I stopped going out for drinks and chasing women after my A-Levels, I simply learned to fit it in around chasing my career!! Do note though that my history is just an example of ways in which you can cock things up, it could be done any number of ways including something as simple as spending too much time driving powerboats........
I admire your determination to succeed and your willingness to prioritise, however do allow yourself time for social and time to do things outside of chasing your career. As you have said, you need to prioritise but I feel it's very important to enjoy a life away from aviation as long as it doesn't negatively affect your career prospects. Don't burn out too young, you won't thank yourself for it later!!
Just my humble opinion however... Cheers!
*By the way, you say alcohol can be dangerous... I'd agree, but so can flying if you're stressed because you didn't chill out with the one beer you fancied the night before
