Sure, I've thought that time traveling is the coolest ability = thing/concept/phenomenon/fantasy. If there is magic so I can use it. = If this were true, I would use it. Until now, there have been a lot of moments that I feel I hope I can turn back time or travel in the past. There are lots of things I reget = regret. But, that is just one of my reasons why I want to travel time = time travel / travel in time. Good moments or terms that I miss also exist. I know I can't use that amazing ability, and it's pretty disappointing but also, I think because we can't turn back time, time that is given for us is so important and precious. And also, I learned that the bad time will turn into a beautiful memory some day. So we have to enjoy all the moments we live. However it's too difficult = It's a very difficult thing to practice.
