Pick a language for me to learn :)

As a native English speaker, I've wanted to learn a second language for MANY years. The only problem is that I'm extremely indecisive about nearly everything. I've spent years just trying to pick the language to learn before even starting. I need to lock in and pick one, so I need help. Some of the languages I'm interested in are Spanish, Japanese, Korean, and Chinese. (If your suggestion is convincing enough, I could be lenient for others). I'm most interested in Chinese, Japanese (especially), and Korean; but I know it's more practical in the US to learn Spanish, so it's also a possibility. (And it's generally just easier).

Any thoughts? (Sorry for writing all of this lol)
