There are a lot of little tricks you can do to inject a bit more time into the day. Most important is limiting yourself to a 40 hour week, not working 50 hours or 60 or 70. It's just crazy. It's actually irresponsible to you and irresponsible to your family and friends. Why should your employer's profits be more important than your own family? You're not even going to get any of the profits - all you get is not losing your job. It's a very negative system.
