Driving cattle for new players. It takes a bit of practise, but it's easy really.
1: You've either bought some cows in a village or taken on a deliver cattle quest for a town. The cattle will spawn on the Calradia map somewhere near the town or village you're at.
2: Work out which direction you're going to be travelling in and rotate the map so you are looking in the general direction of your destination. Get behind the cows relative to your destination.
3: Click on the cows and in the menu screen drive the cattle onward. Here's the important bit: you're driving the catlle, so you need to be behind the cows. Press the space bar and let them get a litlle way ahead, then all you need to do is follow them. If you catch up with them, press the space bar and let them get a little way ahead again. (Usually your party will be faster than the cattle.)
4: If you need to steer them, remember that if you move to the left of the cows they'll go right and if you move to the right of the cows they'll go left.
5: Don't let them get too far ahead as night falls as you may lose sight of them.
6: Don't panic! If the cows aren't travelling in the direction you wish, catch up with them and bring them to a halt, then line yourself up on your target and drive them on again.
It's worth buying one cow and driving it towards a market, just so you can have a practise. You can slaughter the cow when you get to the town and sell the meat. Do it early in the game as cows become more scarce and more expensive later on. And yes, it's a pretty tedious quest.
