Need advice on changing my mindset about sales

Hey guys. I'm a college student and I'm seriously considering taking a d2d sales job during the summer to make some money, and I need some advice.

I went through a training for the company, and all of the training is in line with a lot of the best books I've read on sales, so they seem to be a good company. There's a clause in their contract that says that if a sales representative can't show honest and ethical behavior, they will terminate your contract. This gives me hope that they are a reputable company.

As I went through the training, I realized that a lot of sales tactics (which are in line with tactics that seem standard in the industry) give me vibes of subtle manipulation. It's never anything dishonest, but it sometimes I think I feel like to sell well, you have to play into clients little monkey brains and push them towards the sell in ways they aren't aware of.

I know multiple honest, upright people in the company and outside of the company who are in sales roles as well, so I'm assuming I just need a paradigm shift of sorts. Please respond with your words of wisdom. Help me to feel more comfortable being a sales person.
