Im amazed when people say they been listening for 7 hours a day. i mean when do you find the time?
if im listening while deep focus in my daily job(programmer) i notice my thinking is not as smooth and clear since im bombarded with input i cannot process data the same way as i am not listening to subs.
so if i take out the work time maybe i can fill 2-3 hours max between stuff to do. is it enough? or should i just get used to listening while working?
2-3 hours are enough, with most title can be as little as 1 hour a day. You can also listen while sleeping.
