Tip #14 - embrace total weirdness

Understand that it is different
And that might be one of the reasons for learning the language. Most language learners can attest to the fact that when you speak a foreign language, it can actually feel like you have a different personality or think differently. Aside from the philosophical or other considerations, this has one clear conclusion: you need to think differently to learn it well...

Or just be prepared to think differently
It can be enough to just look at or hear a sentence or phrase and you know it feels wrong. But then you have to bite the bullet, shrug your shoulders and say "This is the way they say it in Spain or Sweden or whereever". Then try that phrase on a native speaker of the language and I guarantee you, nothing will happen. They will talk on like it's normal, or even be amazed at how "native" you sound.

So go on, embrace total weirdness. You'll be better off for it.
