Harry and I are completely alike, except in some very opposite ways. We both like to be organized. HOW that happens, well, very differently.
Getting organized is highly dependent on your personality. One person's "organized" is another's nightmare. There is no one right or wrong way. You have to figure out what works for YOU. Take a look at what we do:
Harry is a paper kind of guy, he likes to spread out. I don't like paper. Clutter makes me edgy, so I go digital. Don't let anyone tell you that you HAVE to do it a certain way. We have a client who lives by her sticky notes. All over the wall. That works for her.
By the way, that's Evernote I'm using on my iPad. I HAVE to have a master "to-do" list plus lists for each client/project, recipes, and personal stuff. I collaborate a lot, share files and info, and need to be reminded to do things.
Evernote is the love of my life (after Harry). I started with the secure free version, now pay $35/year ($2.92 per month) for awesome collaboration/sharing/reminder features. I use it every day both for work and personal organization and it stays sync'd across my desktop, iPad and phone. Yay!
