It seems impossible to complete goals without using gems. Every 5 levels unlocks a stove, which is needed for many of the goals, but sometimes I am no where near an unlock level, or the items take too long to cook and I do not complete it in time. I see a lot of my neighbors complete their goals and have multiple stove items for the goal. Is there anyway to complete these goals without buying/using gems? I fail some goals because of these reasons.
