Any Positive Experiences Training A Puppy?

I’m getting a 9-week old Dachshund puppy at the end of the month and I’m SO excited, however I feel like every post on here is about how incredibly difficult and horrible the training process is.

I know it won’t be easy, but does anyone have any positive experiences training their puppy? I’m wanting to crate train mine and specifically have seen just how awful that was for most people.

I’m also SO scared about getting puppy blues which seams to be inevitable….
