OK, this is definetly a task for the whole life. To be able to tick it of one day I’ve to do the following:
I’ll be moving soon. Instead of writing a mass email to all my friends and relatives I’d like to use the opportunity to write personal emails or phone them to tell them my new address and to catch up with some news. After this I want to contact everybody I’d like to stay in touch with at least once again to then tick this off.
When contacting people I should actually try and encourage them to visit me or to meet somewhere else. Seeing somebody is better than 10 emails.
