i guess that depends on whether or not i kept my current memories/knowledge. if so, way too many things to list. if not, probably almost nothing.
i'd force my parents to put me in a sport. just because i was a girl didn't mean i didn't deserve a work out and a uniform.
What the man in his underwear said. If I could I would like to take more chances and be more outgoing when I was younger. It would be interesting to live life again knowing what you know now.
I would have crushed my sister in fewer competitions, in hindsight it did a lot of damage to her. I would have taken better care of myself. I would have had less pets. (as we have the choice to do things differently I assume we know then what we know now) I would have skipped elementary school, and middle school, and been a polymath, but I still would have gotten a shitty job making glasses, because I need to have. I would have quit sooner. I would have done far less collateral damage. I would do more and fear less. I would have taken that trip when I was 15.
Not dropped out of film school, not ever picked up nugs, alcohol, tobacco, and adderall. Acted less intuitively at times and more thoughfully.
I would have gone to see Guns N Roses at the Metro in Sydney back in 89 Was going to go, one of my friends at the time was keen, and into the glam rock bands, talked about this new band that was shit hot, I'd never heard of them, this was at the start of 89 before they were big. Three months later they were the biggest band on the planet, the Metro is tiny, would have been a cosy crowd of 2000 bopping away to songs from what is now one of my favourite albums One of my biggest regrets
I would start smoking weed at a younger age and I would never start smoking cigarettes. Also, I would not do the things that have gotten me arrested and whatnot.
