Learn English in just 20 minutes a day

Is it possible to learn English in just 20 minutes a day ?
Many web pages affirm this. Reality or fiction?
Put on the TV in English!
Focus on the task.
Obviously, everything will depend on your effort and your concentration. 20 very productive minutes of work a day can make a difference.
Thus, it is true that with 20 minutes a day you can achieve a good level of English, as long as you make the most of it.
Sometimes it is better to work in the mornings, although this is always a personal decision, and you may prefer to get to it during your lunch break at work.
You can rest on the weekend, as maintaining a pace of 20 minutes a day can sometimes cause the opposite effect: start to regress.
You must organize those 20 minutes well, plan your work well: grammar on Monday, vocabulary list on Tuesday … Create a strategy!
Talk for 20 minutes.
If you have an English-speaking friend, call him for 20 minutes. It will serve as an excellent English class!
