You may want to start with a DIY kit on an electronic subject that matters to you
Advantage of the kit is that you'll have a working product in the end, and you'll learn soldering (and other things) on the way. You may not understand all the underlying principles of the kit at first but Rome wasn't built in a day :)
As an example, I started with guitar pedals from techniguitare.com (allowed me to practice basic soldering + refresh opamp theory), then progressively moved to more complex projects. My experience with communities that build these kits is that they are generally very friendly and helpful when you want to learn.
Then, projects like led cubes (i.e. you'll learn matrix multiplexing) or esp8266 based IOT are easy and usually rewarding
