I’ve seen similar lines written multiple different ways and I do not want to embarrass myself on how to say properly. How would you say it ? Thank you

I'm learning Greek currently and would like to listen to podcasts or videos on Greek to practice listening. I would prefer chanells without cusses or vulgar things... I'm interested in cars, formula 1, geography, linguistics, history...

I need a girl to go out with and get into a relationship. If any girl is interested, please send me a message.

I'm currently putting together a teaching resource for primary school pupils about different scripts/orthographies around the world. The task has 18 translations of 'languages are amazing/incredible' in various languages which have differing scripts. I've checked the translations with multiple online translation tools, but I'm well aware that these do not always catch the nuanced points that native speakers can, hence why I wanted to post here for advice.

Would this be a suitable translation for Greek, or is there a better alternative?

Thank you in advance for any help you lovely r/Greek Redditors can offer!
