It may be funny telling someone I love you on the first date, planning your retirement together, or talking about "us" "we" too soon applies too much pressure and saps the spontaneity and fun from the early stage. Hold off for a while until you know each other better. Everything that exist in our universe, as far as I know, has a time scale - including love. Don't be quick to establish yourself as a longlasting couples when you have knoen each other just a few weeks.
The best thing to do is take it slow. Take the time to explore what you both want out of life and see if you're headed in the same direction. While your dreams don't have to be exact, they at least have to be in the same ball park.
