Evening U77. Is U77 a submarine I wonder? feels familiar somehow...
Righty 'O. I gently suggest you find a few things to throw away. I suggest further that those things be symbols of the old and that discarding them is an action of letting go - a conscious practice of throwing away a piece of no longer needed "stuff". Don't necessarily throw away something you want to keep, or even might want to keep, or even might miss not having... instead somethings that u are comfortable discarding.
Tonight I committed to cleaning the kitchen for wife and along the way I found some very dusty coffee glasses that we haven't used for so long they have piled up dust in them and around them! lol. So I decided with wife's help that yep, we don't/didn't need these glasses anymore and I with a smile symbolically and physically threw them away, then cleaned up the dust too!
Wife n I's kitchen now suits our needs a little bit more.
Another option that some business people use is for "poor" clients, just taking them out of the contacts list so one isn't reminded of a poor business customer.
