[NEWBIE] As a beginner should I consider a 7 string as my second guitar if my goal is to play songs that require a seventh string.

I’m pretty new to guitar and have only been playing for just over two months but I have been thinking about buying a 7 string so that I can play songs I like.

If playing songs on a 7 string is my ultimate goal should I just get it out of the way and start learning it now alongside my 6 string or would it be more beneficial to wait a little bit longer until I’m better. I have completed the first grade of the JustinGuitar course and I am learning theory to aid my playing.

It would be nice to get a second opinion on this as I have been weighing out the pros and cons haha.

Cheers
