Everyone has horrific qualities about them, but everyone has redeeming qualities too. I'm sure you and your clone would fight, but I can imagine you would get a lot done too
But you could work as a team with common goals, and alleviate the strain of doing it all alone.
You've never.... pushed yourself?
You're against taking turns abusing what is essentially yourself?
Compromise - you could take turns alternatively having days working and sleeping with your clone.
Assume a clone is free. You could take turns with a clone sleeping in your bed, or the couch, or the floor, or at your partner's, or crashing with a friend.
One clone could go to work doing a gruelling backbreaking soul crushing job, and the other could sleep, for example.
Assume you could sync your memories after each day. What would you do with them?
So you already get enough sleep, have all your hobby projects finished, and are fulfilled in your romantic life?
Nice answer!
You see an exponential curve of interest, instead of an S-shaped curve? Your interests would likely develop rapidly at first yes, but even that will get boring with time and you might plateau at a small community of yourself with dwindling interests, slowly creeping back into single digits, and then finally yourself.
It wouldn't all be for nothing though, you would still have all the fruits and experiences of their/your labour.
