As you're learning, study about ways to improve your soil too.
The best seeds available will not perform well if they don't have a good medium to grow from. So, whether you are making an "artificial" bed with garden dirt purchased in bags from the local garden center, or especially if you are "busting sod" on your property ... things like composting, growing cover crops, crop rotation schemes, etc.. can make a big difference in the quality of your soil and the performance of your crops.
