Based on the posts of Ted Hagos and Sergio Tapai I wanted to share my two cents (literally) on the topic. There are a lot of small little things that can help you get further. Instead of a long 143 items list with small things I wanted to point out two general principles I apply every single day, even outside of coding.
You won't learn how to code by just reading books and watching courses. With actually writing and putting it into practice comes extra obstacles you can solve. These can help you in future similar situations. The opposite is also true, building things is great but always question your own workflow and see if there are any other ways (Shoshin) for solving the same problem.
On a last note, I highly recommend you watch this video about 'The Gap' by Ira Glass. It fundamentally changed the way I look at other people that try to code for the first time.
