Experiences are nice but should a Christ follower really put so much pressure on themselves as the world does to “get it while you can” aren’t we supposed to rest in the fact at the end it all comes back 100times more?
People's bucket lists or wishes may change with different phases of life. The more curious someone is, even as a Christian I believe they will want to do more things like read, travel, pursue new hobbies, etc. The more adventure-seeking, similarly, they might want to travel, skydive, climb mountains, etc. The younger someone is, perhaps they are more curious or adventure-seeking before they set into the routine of life. However, this is not necessarily a good thing that one becomes less curious as they get older.
The world's bucket list may be a bit different, such as getting rich, getting a fancy car, becoming famous...things related to money and fame. Travel and experiences do top most people's bucket lists generally. I wouldn't be surprised if people have personal items but these items just do not make it on popular bucket lists...such as reconciling with someone.
As a Christian, I think travel and experiences are fine but we should also have more meaningful items on the list. Travel and experiences, unless they are meaningful in some way such as visiting homeland, conquering fear, bonding withing someone during the trip/experience, etc. may only produce fleeting moments of happiness. I see what you mean some people have the "get it while you can" mentality such as visiting all countries or visiting all monuments, but perhaps they have some reasons. Personally though, when I limited my bucket list to meaningful items, I don't have a long list.
I know God will wipe away bad memories, but based on some commentary I read we may still remember the good times.
