Seems like a waste of time to go out of my way to do this. I would rather be spending that time building something or getting away from my computer.

However, I do sometimes have to look through code for the following situations.

I can't figure out how something works through the docs. Something I really need to use isn't working as expected. If I know something I'm new to could be done in a better way and I would probably save time by looking how someone else has done it. I need to add a feature to code someone else has provided.

There are plenty of opportunities to look through code other people have written in the normal course of my work without having to set aside special time for this.

Just spend your time coding and be proud of the crap code that you create at first. You will get better!
