Initially I thought to do it as you say, necessarily for different people, but if you stop to think about it, the probability of it happening is very small (if 25 people participate, the probability is 1/25 * 1/25 = 1/625, once every two years about average). So the simple possibility that this can happen and that day you win the prize gives you an extra motivation bonus, the draws are above all that, motivation. I've thought a lot about it and will continue to reflect. Thank you very much for your feedback, it really helps me a lot, it's not just words.
