Call me old-fashioned, but I like keeping a diary! It’s been 2 years now that I kept this one unique diary style from Letts, one page per day, and since I was in school / more indoors / studying a lot, I had to write a lot in there. Now I’m so happy I purchased a Filofax nice leather diary, where I would hopefully write daily & hopefully this will help me be more organized… You can really create your personal universe in your diary, writing about / on:

• Post It Notes – coloured and in different shapes/sizes(rectangular, small, square, perfumed, pink / red / yellow / neon / orange / blue / green, etc) with either lists of things to do, notes from a meeting, interesting things, quotes, quick email addresses, other addresses of people, funny stuff, etc;
• flyers and pictures, add to the diary stuff that u pick up / find / receive during that day, and just put it there… with or without a note;
• the main events of the day – writing down what you consider to be more important for you, either
  - in advance – to remind you about events, calls, birthdays, etc;
  - in retrospective – notes about certain meetings, events, interesting things, important data;
• Thoughts / enjoyment / interesting things – there are so many interesting things that can happen, unpredicted, gestures, some feelings, some thoughts, some nice persons you met, etc – that’s what a diary is about;
• financial stuff – if you feel like these things can be “read” by others, I would recommend that one keeps a record of at least the major things he purchases, like: electronics, major grocery shoppings, books, big/large items, important items/gifts/cards, etc – list them there, either when you buy them(in that particular day), or on a specific list of in/out spending/receiving $$$;
• calls – we make lots of calls every day, and sometimes/many times they are just gossip/chats – but some calls are “milestones”, or more topic-related, overseas calls, or even keeping in touch with old friends, finding news about them… – I sometimes write down the name, duration of call, and the main thing we talked about;
• To Do & Projects – both on a daily basis, working on more important things, or weekly/monthly targets, projects you’re working on with deadlines and milestones, companies that help you/you need to call, etc. Also, what I do sometimes is that I write either electronically or on a post-it note – the things I need to do when I get to a certain place & I am in a certain environment(at home in front of my personal PC; at work when I meet so-and-so, shopping lists, things to do online, things to talk about to someone, etc);
• address book – addresses of the new people you met, either on the daily page u keep, or on the designated addresses list; as you meet people, get their number/email address/mail address, or… the facebook name

and so many other things, from the stickers u get when u go to a certain event(either with your name on it or with some cool design/logo), to pictures, scraps of things, badges from conferences, email addresses from people as you meet them, signatures from people, tell others to write u a note, plane tickets or the sticky band they give u as u check-in, etc – things u pick up as u live your daily life wherever u are. Things to remind u about that day. To make u happy when u look back…. – or sad. Broken relationships, not-so-happy thoughts, etc. You decide what u write/add to your personal diary
