For long engagements: How can you be excited, but present at the same time?

I've been engaged since late 2019 and we're planning our wedding for 2024. We had it planned for earlier, but Covid and College/Job Changes have made it very difficult and we wanted to focus on that first so we don't have to stress about it after we get married + so we can save up more as well. The reason I am asking this is because I would really love some advice and I feel like many other brides would as well that have to wait a long time to have their wedding.

How does one feel the excitement of getting married, but still remain present? When I first got engaged, I remember not being able to think of anything else but us being married, not necessarily the wedding itself, but just the fact that I get to marry the person I've been with since high school. And yes, when you first get engaged, of course that is all you will think about for a while, it's exciting! However, I want to be able to enjoy this time of being engaged without feeling sad that I have a long time still until then. I want to be able to look at wedding related stuff and not feel bad when I'm told that I shouldn't even be thinking about that and to stop getting overly excited since I still have 2 1/2 more years left. Hopefully that makes sense, but I truly want to enjoy the present rather than think so much into the future, because I don't want to miss out on this time either with my fiancé, and I don't want to feel that pain once my wedding finally does come about, that I didn't soak in that time and cherish that time like I do my wedding day and beyond. And also, as many of you know, thinking about your wedding every single day and counting down the days 24/7 is what will unfortunately make time go by slower, at least for me that's how it goes.
So to anyone who has or has had a longer engagement, what did you do to keep yourself present and enjoy the time up until your wedding? Any advice or encouraging comments would be very appreciated! 💍❤️
