Actually, your “dream wedding” is really not correlated with price.
What it is dependent on, however, is knowledge of your heart. This is the knowledge of knowing what you want, and what you do not want.
And the communication of wants is not via words, but visuals.
You have have a high budget, and still not get a wedding you want. Though this is unlikely if you allocate some of this budget to hiring a professional wedding planner who can elicit what you want.
Alternatively, you can have a low budget, but as long as you know what you want, you’d still be happy with your wedding.
The problem with people is that in all that noise, all that societal expectations, all that desire not to be lonely, all that fear–they lose track of what they want. And that’s how you end up in marriages that eventually end up in divorce.
The premise of marriage is important, and so is knowledge of compatibility.
