Thoughts about debt

I believe my thoughts about debt are limiting my ability to grow financially.

It seems counterintuitive to me because I am debt averse and find joy in paying off debt but I am now trying to venture into more real estate investments where it seems debt is necessary to make money. I am coming into a situation where I will have a windfall of money but also just bought a new home with a low interest rate.

My impulse will be to pay down a 2% loan when I want to use this money to begin investing in additional real estate.

How do I change my thoughts about comfort with having debt so I can grow and expand financially? Thank you
