I still consider myself a beginner and I stopped playing completely already twice because of the grind. What helps me on the third attempt is to take it easy. No need to rush tiers or stress about some parts I can’t manufacture fast enough yet. There is plenty of other things to do while waiting, like exploring, tyding up the base, decorating etc. Switching between these and factory building has helped me. Some factories I build intuitively, some using a calculator and others from YouTube videos and forums. And from the latter I learned that there is no right way to play the game. Hope this helps looking beyond the grind.
