Yea true that £150 can be spent on something else. Another challenge in regards to money is living on a budget of 'x' amount for 30 days. Just reverse it. Instead of spending £150, how much can you save?!
It's enough that you really want to do that 'reconnect with an old friend' as not too long ago we spent a WhatsApp message to old friends in London stating that we had been bad at staying in touch over the past year. We want to change that as you can easily lose touch, even in the most connected world to date! Looking forward to see what you choose to do.
Good idea, and definitely will be harder to save than to spend ;-) And so true, I used to send a very long email once every couple of years to my maths teacher (random, I know) so it's more about reconnections like these :-)
