Don't panic and break up your big problem into smaller problems and solve them in a logical cadence.

Also, when you go home at night...turn off man. If you take your work home with you, you will go mental.

Yeah good advices. I remember my first internship 7 years ago, I had to make a SOAP service using Delphi, I didn't know how Delphi worked and what is a SOAP service ... I was alone and during the first month I managed to do absolutely nothing. I began to feel some stress and thinking about this at home all the time. I learned that it's not because you spend all your time thinking about your work issues that you will solve them ...
