Mead is deceptively simple - honey, water, and yeast - but the details make a world of difference. As noted, the ratios are one place to start. Most of my recipes call for about a gallon of honey to 4 gallons of water. The heating process is another element, as boiling the honey is generally considered a bad idea - you want it hot enough to pasteurize, but not necessarily any higher, or you'll destroy some of the subtle flavors of the honey. Then there's yeast - baker's yeast is adequate if you can't get anything else, but brewer's yeast strains are specifically bred for the process - and you'll get different results in the same recipe by altering the yeast. Red wine yeasts tend to give you a sweeter end product, while white wine and champagne yeasts will be drier, with a slightly higher alcohol content. There are also some other additives that are recommended for particular issues, as well - Irish Moss for clarity, tannins from grape skins or black tea which also reduce hazing, lemon juice or citric acid or other yeast nutrients to keep yeast going in a 'stuck' fermentation, etc...
It's a process. If you've got something drinkable on your first attempt, congratulations! And don't rush it - most homebrew meads don't really get good until almost a year has gone by.
