Can a Flute player learn to play Trumpet, without forgetting how to play Flute?

Ok, I didn’t know how to write this question lol. I play flute in my school band, signed up for high school band, and I play in a marching band. I am still going to be taking flute in high school and learning more. I am planning to have a career in music maybe when I am older, and I would like to play more instruments. Everyone says that if you play flute and want to take another instrument we have to take saxophone or clarinet. I heard that it is best to learn trumpet for a music career so thats what I was planning, so if I took trumpet would I forget flute or something? I would still continue learning flute, and playing in a marching band, I would just like to learn trumpet on the side.
Thanks so Much!
