Most MTTs only play around 1 in 7 participants, so not cashing 3 times in a row is not even a bad run. If you were "almost there but not quite" every time, that can feel a bit annoying. But at the end of the day it does not matter, if you bust after 20 minutes or 3 hours, at least not for your financial results. If you bust after 20 minutes, you might actually end up losing more, because then you have more time to play another tournament. To even just somewhat overcome variance, you have to play at least 100 MTTs every month and ideally even more. So dont get hung up on meaningless short term results like this.
