You certainly have a lot on your plate and deadlines to meet. These thoughts you have of preemptive failure feed off of your current inactivity. Once you find the will to defy the negativity and turn the first page the rest should guide you. Another mistake is not breaking the challenge down into digestible parts respective of any time frame. School was always a daunting 8 hours for me as a kid. Constant counting down of the clock while growing more and more impatient. Eventually I found that by cutting the 8 hours to two 4 hour sessions I felt less threatened and more accomplished once the first half of the day was done. It was still 8 hours of schooling of course, but by changing my perception of time (challenge) I could mentally tackle the day. I would recommend this in your case as well. Maintain a decent work rate, but structurally cut your perception of it in half. After you've completed half you should feel confident enough in victory to go another round. This strategy has worked for me and feel strongly enough to extend it to others. Results may vary of course.
