I want to help junior/mid developers. Tell me what is/was hard for you to understand and let you grow.

Hi,

I want to do a series, either blog articles or short videos to address common questions/problems which young developers struggle with.

I have some in mind from my past, but it's just my experience, while I would like to help a broader community of developers to understand stuff and grow.

It can be stuff about coding itself, but also stuff around architecture and so on.

I will appreciate your help and promise I will get back with answers!
