Learning English without practice

It's commonlyhear common hearing people say "English is so difficult. I can read and understand that I read, but when someone speaks english I can't understand anything and, If I have to express my ideas I can't speak out because just in that moment I forget all that already know". Another says "I want to study English in a good Institute" and when they found it, they want to speak English in a month, and after that month they became very frustrated because they don't get the level that they want. That's because only study in the institute and the rest of the time they don't practice nothing. A big amount of persons person thinks
 think  that exist "a magical key" or "miracle pills" to speak English from one day to another and that's not true. If you want to learn some language you have to dedicate... I don't know, maybe a couple of hours every day, at least one hour... but practice!. If you don't practice you'll never learn it well, or you will lose all your skills or simply will take you a lot of time to learn it. Maybe one day you can practice writing, another day listening, other speaking and don't forget to do different activities for each one to not make the "study time" in a routine. Thank you so much for read and fix this.
