Doubts

There are days when I think I'm just not cut out for this. I've had a lot of those days lately. I just can't seem to get my head around this analysis and computing stuff. I guess I just don't spend enough time on it. But I don't like it, don't get it, and am not interested in it. I suppose it's no wonder that I can't figure it out when I don't spend extra time reading miles of TWiki pages and code.....I just can't make myself concentrate. I don't know what it is. I never used to have problems learning things. How the heck am I going to do an analysis, write, and defend a thesis all in the next 2-3 years????
