Track finances (which I would be a complete mess without), healthy eating schedule, all of my poker documents separated by tabs - also track wins and losses and taxes to pay, stock footage info sales, my offsite storage, camping gear organized in tabs, screenwriting notes by tabs…I have lots of excell documents that make my life incredibly more easy lol - using the cloud is awesome, can update by iPad, computer or phone. Using excel by phone on the go keeps my finances in total check.
Also If you separate expenses by name it can automatically put into a graph so you can easily see what you are spending on per day, month, year etc. Its pretty damn amazing once you get used to it. There are some amazing templates for cheap on Etsy instead of creating your own.
