Started Practicing

I've played 3-4 rounds a year of golf for the last 10 years (mid 30s ) I've broken 90 one time and 100 is usually the goal. I decided to start going to the range as well as chip/putt area. I've seen pretty drastic improvement with my irons where I can aim and hit the landing areas with some regularity. And have gotten better about not 3 putting in practice. I plan to play 9 holes in the near future am I about to be really humbled or will it be really fun now that I feel kinda comfortable standing over a ball?
