My advice would be if you are very beginner then learn basics from videos then just start your models (don't go too high)
I would say exactly the opposite: choose a complex object to model, find a full tutorial and follow it step by step. Knowing english and the very basics of modeling will be enough. When you start doing complex things you automatically learn the intermediate options/tools. The aim of this way is not creating something spectacular but to lean almost all the options of the program you use and to be able to play around with them. And I assure you that even if your final result is something ugly, you will see it as a master peace no matter what, because it's yours and you evolved with every vertex created in that model, it will be something that you will sympathize even when you will have other much better models

As an e.g. this was my very first model (except a box) that I made and I was so proud of it and I felt like I'm one of the best modelers I've ever seen, but now I am looking at it and I realize how plain, simple and stupid it is.

An example of a video that you may want to try, here:
But if you want to use Blander further than you will have to find your own video.
