Here's a really unique concept I came across a couple of years ago called Futureme. It is a website where you can write an email to your future self. You choose the date and time for when it will be emailed to you as well as deciding if the email is private, public or 'public but anonymous'.
So what to write? Perhaps some words of inspiration? Maybe details of what is good in your life right now so you remember it clearly and look back with appreciation and gratitude? Or look ahead and write as if you’ve achieved all your goals and dreams for that date (which would be a good way to add a deadline to a goal).
Grab a few minutes to let your mind wander and be creative, then write a note to future you, which will be read from where-ever life may take you .... exciting! http://www.futureme.org
