I take myself to those places some days. My past. I don't want to relive my life. Those good times and bad times from back then were important. If I feel like it though, there are a few things I can do to go back in time.
I don't mind picking up an old Nintendo game I used to play a lot when I was young. That takes me back to that world. I'll also hop on my dirt bike and hit up my old trails and back roads. I used to spend a lot of time in the middle of nowhere on a dirt bike. It's easy to do it all again. I find it helps.
I happen to do something very similar, I was searching for some old playstation games and for years I couldn´t find them. Lucky me found them a few days ago and I´ve been playing as if it was 1998 and I realized it was about nostalgia, I wanted to play them to remember how i felt 20 years ago.
I´ve been wanting to visit my old school in Mexico city and the places I used to hang out in, I think that will help to bring back some good memories...
