Here is the great project for you...
# To think about people who have made an impact in your life
# To relive your moments with your old friends
# To say a small thank you to them before we get on with our own ways.
# To fill you with immense gratitude and reminiscence
What is it: Making your Gratitude list from your memory.
How: Run your flashback reel of your life in your mind and jot down how many ever friends or acquaintance names you remember.. starting from when you were small (whatever age you can recollect) until now.
Do not use Facebook, Mobile or any other contact resources to refer. Just use your head!! That's the crux of this idea.
Run your Life Journey once more in your mind! Take some time for this activity... shut off from everything else. In the end you would be amazed how many are still in your mind and you never had time to thank them even!!
