Any tips to navigate the limitations of an old M43 camera ?

Hey everyone, I bought my first camera around a year ago. It's nothing fancy, at first I wanted to get some practice and see if I can commit to this hobby before moving on to something more expensive and bigger.

It's a Lumix GM1 which I got for a very good deal, and I bought a lumix 12-32 and a Lumix 25mm 1.7 to have a zoom and a prime.

The issue is I've been hitting some limitations with this gear since it's kinda old now, and I'd like to know how you guys work around them, how to set it up, which tools are at my disposal, etc etc

Thank you!
