Привет! I'm currently learning Russian as a native English speaker. I've only been at it for a few weeks but I feel like I've gotten some of the basics down.

Anyone who is more knowledgeable than me, how do I reliably learn which to use from ц, ч, с, щ, or ш?

Also when speaking long words 10+ characters or 4+ syllables long I feel myself triping over my tongue. Moreso than my previous experience with learning German but it has been over a decade since then.

Additionally, anyone else learning a second or third language and hows it going for you?
