You can do it man, you are already aware which is what matters now just smoke one and read as much and as many subjects as you can you will eventually find yourself lost in so much info that internet has for us, lets take advantage that we are the internet generation and we can literally do whatever we want but dont forget that to get what we want we have to study and work hard that why we should always look for those things that we love and if it doesnt work then try another thing simple but not easy, good vibes man
