Consistency tips?

Despite my interest in language learning being genuine, after a while it begins to feel more like a chore which makes me lose motivation pretty quickly. I'm starting up another language in hopes I actually keep learning and eventually reach fluency so I can study abroad.

It's not that my target languages lost the exoticness they first had, if anything I like when a language I'm learning begins to not feel foreign anymore, It's just that staying consistent with things is difficult for me.

I've been through 4 languages by now. (Dutch, Scottish Gaelic, Arabic and Spanish). As of now I'm studying Korean, I enjoy the language and hope I stay on track so I don't make the same mistakes I've done previously.

Any tips would be appreciated.
