One "fancier" tool I did tell my friend about, however, was Yast.com, an online time tracker. It has become absolutely essential to my work life. I heard about it in the fall in a Forbes article listing several "must-try" online organizational tools. I tried a couple of them, but Yast is the only one I've found to be a must-use.
I actually started using it when I was full-time at my old job, just to track how long I was spending on certain tasks each day (a very educational exercise, I must say). And now that I'm a freelancer, billing some jobs by the hour, it is even more important to know how long I spend on each job.
Whether you're tracking paid work by the client or project, or just want to know how long you're spending each day on various parts of your job or various other activities like email and blogging, I really recommend this tool.
