Why would it be? I sleep with my lamp on. I don't like it when it's too dark in my room. But I did used to sleep in the dark. I stopped because we had mice, and I used to hear them scratching at stuff. It also made it easier for me to read without turning on the bright light. The dim light of the lamp is just right for me.
How do you deal with unpleasant tasks? Do you complete them at once or put off until the last moment?
I hurry up and get them out the way, so I don't have to worry about them anymore. It also depends on how big of a task I have to complete. If it's a big task. I do a little at a time until I'm done. If it's a small task. I do it all at one time.
