Busy days

Recently, I'm working with custom's new product. It is terrible for me due to I need to focus on both NPI and Sustaining. My engineer can't make NPI well so that customer asked me should be involved. Then I need to waste all my vocation and personal time on it.
I'm interesting on cooking now, so I like to go home early and cook by myself. It's funny and I enjoy in it. These several days I need to skip it because I have no time on it. I hate it.
