I'm not sure if someone said this already, but I simply focused on staying consistent. I would get one or two pars with a lucky birdie once in a while, but I'd have a couple of triple bogies bringing down the whole score. I had a decent swing form so I knew that breaking the 100 was more of a mental barrier. My dad told me to try and aim for an all double bogie first, then slowly bring it down to all bogies. I just pretended that a bogie was a par, and it kept me from trying ridiculous shots or being too greedy with distance. It takes time but now I feel like I have much better consistency in my scores.
