I loved Lotus, but had to transition to Excel.
Lotus 123 was all the rage in my 1980’s office days. I never learned it.
But by the time Excel came along, I became proficient with that and have been using it ever since.
In the mid-80’s, I was in grad school (MBA) and learning/using Lotus123 and WordPerfect.
Ahhhhh, those were the daze my friend, I thought they’d never end....
Later, I transitioned to Excel and Word....and still have v2007 on my laptop that functions just fine for my entrepreneurial endeavors.
