Whether you use an app, take an English course, hire a private teacher, or do it yourself, there are ups and downs in learning English. 
 
One thing I've begun to notice is that people tend to blame themselves when they don't reach their goals for English. 
 
Then they feel bad for not being able to learn.
 
I say: judge your English learning technique by how much your English improves. Stop blaming yourself and feeling guilty. Figure out what you need, and find what works to make it happen.

You are not a lost cause. You just need to find a method of learning that works for you.
