What do you do to keep your game interesting?

How to keep my sims game from boring me to tears - is dream about how good it could be, then make more new sims, form a new story in my head for them, make them a new house and stay with in their budget, and make them earn money to turn their simple abode into their dream house - that usually last all about 3 sims days and by then I want to pull all my hair out a strand at a time because of the monotony - so I shut off the game and go play one of my many years old Sims 3 save games where all kinds of stuff is going on, or I go play some of my still in redevelopment save games I have growing in Sims 2 and try to forget Sims 4 even exists for rest of the week. That goes on for another week or two, then I can try again in Sims 4, make another new set of sims, another house, same-o, same-o. As I really hate it I cannot seem to go back to sims I was playing in Sims 4. The game will allow it of course, it is my brain that won't allow it as it reminds me of how the story I pictured for my sim was not happening no matter how hard I tried - so like a dummy I try a do over thinking a new idea will work - and as usual ends just like the previous 30 ideas. Funny though I have no issues playing old saves and households in Sims 2 or 3 - infact get anxious to go back to them all.
