In science, you never just perform one test and move on. You always perform multiple tests and stick with the one that did the best. See, it's the same with life, it's all about chance. You're not always going to win the perfect bet, but you will someday be on that winning streak that pays off for all the hard work you had to go through. So remember this:
"Life's progress comes from trial and error, and your hard work will be paid off by that one winning streak." ~Tech4K
