I have trained myself to have patience. When I know by experience that loading a SW(so, not only flightsim's) takes a certain time, I start it up just before I take a small break like drinking coffee/thee, toilet-visit, open the browser and verify the news-headlines. By return to my 'gaming-place'(PC or Laptop) after let say 5 Min, the started SW is ready to use...and to enjoy....
In the daily other activities, when getting older, you learn to have patience and relativate life more than younger people + I'm not active on social media platforms 🤐.
