Get an aeropress or a hario switch. They’re both super easy to use and give good coffee. Plus filtered coffee is slightly healthier cause apparently some of the not so good for you oils get filtered out.

Then either buy some ground coffee from the supermarket or for better quality stuff go to a specialty coffee place and ask them to grind a bag for you. They have good grinders and according to some testing a week old coffee from a good grinder is better than fresh coffee from a cheap grinder.

Then just try different coffees until you figure out what you like and don’t like then when you’re hooked you buy a good grinder and that’s it.

I’m gonna go against the grain here. Go to a coffee shop (preferably not a chain), tell them you are new to coffee and want to try something mild to start, go from there. Try different kinds of coffee, ask their advice. Once you find one you like ask them how THEY make it, what kind of beans, how concentrated, etc. Then you can start figuring out how to make it yourself. Maybe it’s a common enough coffee you can find in a K Cup, maybe it’s one you need to brew yourself in a coffee maker (which becomes a whole different question), but those are later things to figure out. Start simple: try some coffee, see what you like.
