I had the original iPhone also. Didn’t get it day one, but I did on the first restock. I was only in the 9th grade then. That thing didn’t do much, but I remember being the first dude watching movies in class. Movies that I had to download on my computer then upload to my device bc there wasn’t even an App Store back then. and edge... don’t get me started. 
Times have changed so quickly. 

Yea I don’t do betas. Definitely not on my MacBook pros. I just avoid the headlines and temptation doesn’t get to me. 
I will say, the jailbreak on my iPhone XS is godly. I love what it’s done to my device. 

I’m sure you’ve got a lot on your lap with that NZ trip. But just know all kinds of people who don’t even know you irl (like me) believe in you to succeed. You surely can trust yourself to kick ass and enjoy yourself both. You’ve got this. Once you’re in the air most of the built up stress will die off anyways. Then you’ll just be left with the actual work itself and not so many what ifs.

Goodnight to you, off to bed I go. 👋
