how do I handle change and uncertainty

I love change. change keeps the life interesting, but lately I have been dealing with a lot of stress caused by change. I realized I hate it when business and work things change suddenly and someone cancels, cause I like to get the most out of my time and sometimes it's hard because I try to be in 2 places at once and think to myself now that person x canceled I could have actually done the other thing, attend the other event. Then it's not possible anymore because the time window is too small and I hate that. It's not like FOMO for me it's just with certain things I would love to work for/with or attend cause I know they will inspire me and then nothing of the 2 are happening. Sometimes this sudden change though is in my best interest because don't take time off so much and therefore those circumstances push me towards relaxing. Change is inevitable for growth. I would never dislike it. Uncertainty keeps the spirit alive, but also recreate time for doubts. It s beautiful and terrifying at the same time. I always felt with it after finishing high school because I went to foreign places and saw very different things, met different people and tried out different jobs or the same job in different places. I like to wonder. Working with horses is different everyday and modeling brings a lot of uncertainty as well. releasing music does too. you just never fully know the outcome and response of anything. can u do well with change?
