Anyone like to improvise?

Hi. I have always had a desire to be able to sit at the piano and just play - without knowing what I will play. It seems to be a daunting task, but since I found a great teacher who was classically trained before becoming a professional jazz pianist, I have made some progress. When I don’t feel like practicing I sit at the piano and play a simple chord sequence - for example Fm7, Bbm7, Cm7, Fm7 - and find notes and phrases that sound good to me.

Does anyone else improvise or plan to learn how to? It would be good to share ideas.
