Well, good news then: lvm comes with most modern linux distros. In fact, it is an option you can enable when installing linux mint.

I use it on every system that I run (workstations and servers) and never had any issues.

It really just makes partition management way easyer: With normal partitions you cannot grow any partition without moving all other partitions after it. LVM can do it without touching anything else.

The best case for semthing like this is when you buy bigger ssd. You can copy the data with dd and then grow any and partitions that you want without hassle.

I recommend that you take a look at LVM. It can help you manage your partitions without much planning beforehand.
