I want to become a pilot

I am saving most of my money from paychecks and use it for flight lessons. Each lesson or flight is a minimum of 1 hour long. I pay about $130 for each hour, so it's pretty expensive. I have only done my introductory flight which was 30 minutes and I enjoyed it a lot. I am planning on becoming a commercial pilot and working for some cargo company like UPS, or Fedex. I hope everything works out good.
