I fucked up big this time. I was supposed to have a TEM session with my advisor early monday morning. I didn't quite finish up all the sample prep this week, so I was going to come in on the weekend and do it when I can have the whole place to myself. Unfortunately, I forgot that I don't have keys to the sample prep lab. So now I feel like a big fool, and I have to tell Tom we can't do TEM tomorrow. That also means we have to make up that session either at night or during the weekend because the microscope is booked solid until mid-November. I was lucky to get that monday, and I threw my opportunity away because I'm a dummy. Sometimes I wonder if I'm really cut out for grad school. I have very little motivation sometimes.
