Wedding planning

Hey guys so I just got engaged and I’m super excited to start planning my wedding. I just always new how I wanted certain things for my wedding so I’m ready to start. I got engaged 2 weeks ago and already know what venue I want and I made an appointment to go see it and be sure I like it but some people are telling me it’s too soon and I have time. I just want to have the venue booked so it’s one less thing to think about am I moving too fast?
