Question for first time horse owner

I just bought my first horse and have a question for experienced equestrians. I leased for a couple years before purchase, so I'm really looking forward to owning my own and to see what we accomplish together.

My question is - can you train a horse to be in front of the leg? My trainer told me I needed to get a "kick ride" horse as an amateur. I understand the logic for safety reasons, but now during lessons I am SO TIRED because I have to keep kicking my horse to go, and sometimes I can't get into the canter either.

Now my excitement has kinda turned to frustration because it's hard to keep a stable seat and enjoy the ride when I feel like I'm fighting with my horse. So is it possible to train him to be in front of the leg? I hope I didn't make a mistake in buying him.

Thanks for any input. Appreciate it.
