Too much stuff

I have just too much stuff to keep track of. I need to come up with a better way to do so cuz my head can't keep all that information in. This is the list I have come up with so far

• School stuff (when to bring what, library day, school admin stuff, parent teacher conference etc...)
  
• Home stuff (laundry, cleaning, home projects etc...)
• Money stuff (Bills thank goodness for online billpay, tax, retirement, money management...)
• Admin stuff (citizenship, etc....)
• Training stuff (that's why I have a coach but I still have to manage my time...)
• Work stuff (well I do have a full time job and it fills my head quite nicely )

I'm sure I'm forgetting a lot of stuff that is cluttering that tiny head of mine! Now back to work.
