I learned on Lotus also.Lotus was the shit... The Godfather of all spreadsheet programs!
Lotus - the first wife that's 40 plus, gained a bunch of weight, doesn't have a job and bitches about everything including when you want to have sex. Comfortable though.
Excel - 30 years old, super hot, super tight, body, fun to hang out with, has a good job and loves taking it in the ass.
Google sheets - 22 year old that looks like the 30 year old but too stupid to have a conversation with, underachieving at work, fucks when you want but you know she's fucking around. You just haven't caught her yet.
