When you first spawn in your small and move faster than you want to. And because the food your eating is small its hard. So what I like to do is line my cross-hear up with the food and then look down at the floor towards my self. And it make my hand more steady. Also when you get to 10 mass you can eat the next size up mass. But wait till you get to 11 mass before you try to eat it. Because if you dont you could be like 0.1 mass too small and you wasted like 10 seconds getting to that mass. Also dont spend all day on one food. If you miss a food keep going forward and aim for the next one in front of you.
