Reaching the 100k milestone

I've been seeing a lot of youtube videos along the lines of "why your net worth explodes after your first 100k". All explained through compound interest, how fast you can grow from there. This is very exciting for me as I'm going to hit that milestone of 100k in liquid and investable assets this year along with my business partner and who we consider each other brothers. We both dont own property and have no mortgage. We're looking for ideas to celebrate. Not that we have to spend anything big of course because that will defeat the purpose of the milestone. He lives in Melbourne and I live in Christchurch. I'm thinking of flying over to him since he flew here earlier this year. We love hiking but we already did a 4 day track while he was down here recently. Edit for more info: We are in our late 20s and will each hit the milestone individually Any ideas on celebrating?
