It is normal to work overtime every day, and stay up late less every day. Do graphic design to see who you serve. If it is a printing shop or an advertising company, it basically works overtime every day. If you work for a company, work overtime when you are busy, and play soy sauce when you are not busy. I'm just doing graphic design now. Now I have a weekend off, a normal holiday at ordinary times, and work overtime once a month or two.
