I worked fulltime as an employee and entrepreneur [I Am Determined to Be a Successful Entrepreneur]

Super exhausted. I would like to say it wasn't easy. I was totally super tired and my brain needs space up. Then you will asking me why do you have time in SW?. I will said it's because i need to entertain myself and make a distance for a lil bit. It's because my fulltime job in company consuming a lot of my time. I handled really big telco project it effected a whole my current mood. Anyone has experience worked as a fulltime employee and run your own business at the same time? Please share how do you cope with it?
