The Beautiful Dream of Nikah

Assalamu alaikum, I'm from Pakistan. For about a year now, I've been completely absorbed by the idea of marriage-I just can't stop thinking about it, and honestly, I don't want to. The vision of a pious, kind, supportive, and blessed wife fills my thoughts, even though I know I need to better myself to be worthy of such a blessing one day. Sometimes, I feel social media feeds me endless marriage content, and maybe youth plays a part too. I often daydream about married life: imagining everything from a simple walima with family discussions, to standing up for my wife's Islamic rights as the only son in a Desi family, to working through disagreements together, and sharing moments of love, care, and everyday joy. I realize marriage isn't always perfect-there will be challenges and disagreements, and it won't be like a movie-but the dream still warms my heart. I don't want to delay marriage until I'm much older or until I'm 'successful' in a worldly sense. In sha Allah, I'd love to marry young, perhaps before 21, because I believe a wife isn't someone you meet at the finish line, but a companion who walks the path with you. Just thinking about that companionship gives me so much hope and motivation. Is this focus a good thing or should I set it aside and concentrate on the present? Are my thoughts unrealistic? I don't really have anyone to talk this all out with, so it's been building up inside. Would appreciate any sincere advice.
