Listening / Understanding

Aviators, airplane pilots, never speak of their experience in terms of years. They accumulate experience in terms of flyint hours, actual flying time: 3000 flying hours, 5000 flying hours.
Our experience in a language should also be gauged in terms of exposure hours. But this is difficult, of course. However, time is of the outmost importance, especially in LISTENING, in acquiring sound experience; in giving our brain sound input in the new language. The more the better.
Our brain must get hold of the new sounds, become familiar with them; frequency of input will ease the learning process and familiarity with the "foreign" sounds.
May I suggest you listen to English or Spanish on a daily basis? YouTube is there to offer all kinds of accents and levels and subjects... Please listen to your language of choice 10 or 15 minutes a day, everyday!
You will learn sounds, words, expressions... But listen actively. Do not allow your brain to roam listlessly... Listen!
