Career break

Professional development

Nov 2023 – Dec 2023 Ā· 1 mo

  • I hatched a plan that was about as well-thought-out as a cat's strategy for chasing a laser pointer. I'd take a break, enroll in AI courses, and transform myself from a mere mortal into a data-wrangling superhero. My mission? To vanquish spreadsheets with the power of Python and bring justice to the land of big data.
  • So, I made the bold decision to take a break from my current job and delve into the world of AI. During this hiatus, I would immerse myself in AI courses, collaborate with experts, and stay updated with the latest advancements. It was a leap of faith, a departure from the familiar, but it was driven by a deep passion and a desire to align my career with my true calling.
