I woke up late for my dog-walking job on monday
Why do you think that you overslept?
I'm overworked. I got off late from my other job and overslept.
You need to step back and consider the toll of working so many hours is having on your health. Consider cutting back somewhere.
It's fine, I'm too busy to notice. I'm a quarter of a way to becoming extremely successful.
I think that you might be overworked though. I know that you want to be successful, but if you are too tired, it can be bad for your health.
