I am a Charter Professional Account (CPA) in Canada who discovered Power BI, Power Query and Power Pivot a few years ago. I have occassionally used Power Query through work for 3 to 4 years but in early 2021 I started to make an effort to learn more about Power BI and now in 2022 I am devoted time to keeping learning Power BI but put my new skills in to practice by doing hands on work - mainly volunteering but hopefully transition into a paid role.
