Indeed - in cooking, technique is supreme when it comes to to creating great food. So many new cooks get hung up on precise measurements but don't consider time and temperature and don't ask themselves why they're doing certain things at certain times. With time you begin to acquire a bit of an intuition about how much of whatever it is you might use and you learn quickly that you can always add more, but you can't often take something away.
You should also be able to answer why each ingredient is being added - what is it trying to add, complement or remove if it wasn't added. And also remember that you can season and spice as you cook. You should always taste while you're cooking - it's a simple thought but so many people don't and once you find discipline in tasting while you cook, you hit a new level.
Now baking - yeah you better get your measuring cups and scales out!
