Does anyone know of a piece of software that has helpful functions to help you keep track of various jobs you are doing?

I need this cos im working for a friend whos giving me lots of unrelated small jobs. For example, one task is that i need to transfer a sum money to an international account, wheras another could be to bulk order some envelopes.

At the moment im using nothing but a .rtf file, and its starting to piss me off. Not a very sophisticated way of sortin' shit.

Does anyone know of any software thatll do the job?

P.s. I dont want to create myself a database, i dont have the time.

Ideas?

google desktop tool bar or google homepage and add to-do-list to the homepage.

Also, writing it down on paper and scratching it off when your done is useful.

outlook has a calendar you could use
microsoft project I think was designed for crap like that
you could use excel or access to slap something together real quick
if this is going to be long-term, I'd recommend building a web app to do it using mysql and php.

nextaction is awesome. make sure you actually read the instructions.
