What do you personally dislike about learning a language? Work out what it is and avoid it.
Why do I suggest that?
The rationale for this is that there are countless way of acquiring another language. That being so, you may as well choose a method that doesn't rub your fur up the wrong way.
I mean, our goal is not to build moral fibre!
Avoid what you dislike. That way you are in less danger of quitting.
So if you have doing exercises, don't do them!
If grammar ain't your cup of tea, don't drink it!
If the thought of speaking to a native speaker makes you break out in a cold sweat, don't sweat it!
Just stay shtum.
Naturally, if you give into every impulse to flee, then you may need to be a little creative and inventive about filling in the gaps. But that's doable.
The main thing is to avoid those off-buttons.
There are always other ways and means.
