I posted this before looking for topics, but it kinda ended up being online support for general bicycle troubles.
Which is a good thing! Ask your questions about bicycles that are currently on your mind and we all try to help.
Pre-Emptively calling in @dallasw and @Kissmydadonthelips for their knowledge.
How do I change a flat in less than an hour? I suck at this and my roads are shit poopoo

Do you have tyre levers?
I do. I probably need practice as the other comrade suggested.
What helped me on this was understanding that the tyre gets clinched to the rim by the tube (well, unless you're running tubeless) and then understanding that you need a fixed point on the wheel to work out from.
For the latter, I usually go opposite from the valve to work my way to it on both sides and I found it a lot easier when I understood it as removing / fitting the tyre from one point to another rather than all at once, basically.
Also put a bit of air into your tube to help with refitting.
