Am I enough for my pup?

I recently adopted an aussie x border collie and I’m starting to feel like I’m not enough. Family says I’m over thinking but I just want to be sure she’s happy/healthy.

I WFH at a desk 8 hrs and throughout the day. I take her out and we get a fetch or play sessions in, I walk her in the morning and night, give her a frozen Kong mid day and take her do the dog park once or twice a week. I’m trying to get her steady walking so we can eventually add hikes to the week but I don’t thinks she’s ready yet.

I know these breeds need lots of stimulation as they’re very energetic so if you have advice on what more I can do or add to the schedule please let me know.
