Having been married for the last 12 years I probably have a bit better perspective on the subject than some. It is totally worth it, assuming you start off with the right woman. Make sure the short time you have known her has been adequate to determining if you want to be with her for 60 more years.
At the end of the day, it doesn't matter how you proposed, it matters how good of a husband you have been when you are both 90.
The wedding is her day, the proposal is your bit to get her there. BTW, you don't get a day in there anywhere.
