Yes sorry, the advice did go a bit downhill

but as Connor said, there was some serious advice there which would be perfect (in my opinion at least) for a beginner and Connor made some excellent additions too..
I would add to this that if you are just starting, really try not to worry or obsess at all about time and depth. Just learn to be comfortable in and under the water and relaxed. If all you can do is 1 min (which I can guarantee you if you did a course you'd probably realise that in a day you'd be able to do double that at least), then that's 1 min of enjoyment
The beauty about freediving is that you can just keep diving - it's better to enjoy yourself in Maui and snorkel and do many short dives whenever there is something you want to see closer rather than try to do deep, longer dives that you will probably not enjoy much at this stage and will not be safe either.
When I was at the Maldives a couple of years ago, I mostly snorkelled (although I could freedive) as I didn't really have a buddy and just did shallow dives whenever I wanted to take a photo etc. While it would have been fun to have a buddy and go a bit deeper, I have to admit that I had a brilliant time even just snorkelling - most things to see are within the first 5m-6m anyway so you really don't need to go deep to have a great time.
Maybe just go on the snorkelling outings so that you have some people with you to watch you and just try duck diving down to 3m-5m and equalising and then coming straight up. If you can become really comfortable doing that then it's a big first step.
Resist the temptation to go deeper or hold your breath for longer, stay well hydrated and breath at the surface normally for 2-3mins between dives...
Have fun and dive safely.
