Activity vs. Action ?

My idea this week is “spend more time with my Dad” and reason why is “he has Parkinson’s and his health is failing so I want to maximize our time together”. I live in SC and he’s in CA. So today the homework was to do an action that creates a result towards my idea… I know that researching flights is activity… but here is what I did that I think is action, please correct me if I’m wrong… 1. I talked to my Dad and got his OK for an April visit… 2. I talked to my ex and made sure he would be ok with me leaving for 7-10 days and he would handle the kids… 3. I applied to petsit for someone in CA so I would have a free place to stay (but have not gotten a response yet). And then actually buying a plane ticket would be an action, correct?… Thanks!
