Thank you very much @realfast8!
I'd say definitely at least check out some of the to-do lists out there, they are getting pretty sophisticated and have some great functionality.
The one that I use, Wunderlist, which was bought out by microsoft last year has some really great functions which I use to keep track of my 100+ tasks which I have arranged according to priority and in different folders set accordingly.
Best part, it's free! Wunderlist.com
