The first and third reason are both about exciting. It seems you are not ready for the third reason, but since there are some seconds left, you managed to find one. That's not right. Try to give only two reasons, but more content. Try this pattern for Q1-Q2:
first 1-2 sentences: introduction. my opinion: A or B. agree or disagree. about 5-10 seconds
First, reason 1 (1 sentence) + why reason 1 (some arguments. 1-2 sentence) + a small conclusion for reason 1(like advantages of reason 1 or comparisons if not reason 1, 1-2 sentence). // about 15 seconds
Second, reason 2 (1 sentence) + why reason 2 (some arguments. 1-2 sentence) + a small conclusion for reason 2(like advantages of reason 2 or comparisons if not reason 2, 1-2 sentence). // about 15 seconds
Conclusion: Don't need a conclusion. (you can have one only when you don't have something to talk about)
-----------------------------------------
An example (Eating at home or restaurant) for First:
First,reason 1 (1 sentence: Eating at home can save money) + why reason 1(some arguments. 1-2 sentences: I can prepare cheaper food from food market; I don't need to drive or take a bus to reach the restaurant;) + small conclusions ( 1-2 sentences: with the money I saved, I can buy a good book to read; I can use the money for a trip...).
Suppose sometimes your mind is empty and had no ideas how to talk, don't forget that 'save time', 'save money', 'find a job', 'make friends', 'get more information' are reasons that can be applied to all speaking topics.
