If you are already pretty proficient in coding, I would take a break from it and instead learn something different.<p><pre><code>  - Sport (Snowboarding&#x2F;Skiing&#x2F;Swimming, Climbing etc lessons)

  - Reading books (History, Biographies, etc)

  - Visit a new town (doesn&#x27;t have to be too far) and hangout with complete strangers and learn their stories.

</code></pre>
Or purely on the STEM side you could refresh yourself on probability, statistics, linear algebra and get a deeper grasp on machine learning&#x2F;data science.
