Well, that's a cheery thought. But a wise friend of mine once asked me 'what would you 80 year old self say to you about what you are doing with your life?' Even if the answer is 'crack on, you're doing fine', it's worth having a re-evaluation on a regular basis, because finding that you are too weighed down with responsibilities, commitments, or time-wasting activities (social media games, anyone...?) to actually celebrate what's important in your life can be a sobering discovery.
It's the same with 'stuff'. Every so often, have a look around you and assess what you have - and get rid of whatever doesn't enrich your life by either being useful or beautiful, or preferably both. Having a sort-through of your accumulated and/or recently acquired possessions can help to clear your mind, give you a sense of achievement, especially if you did a big declutter, but nothing since, and felt a bit guilty about 'falling off the wagon'. However, it's my opinion that there is no wagon - there is only you, and your journey, and there is no guilt to feel.
With that in mind - We recently took a trip to an amazing country, and came back with cameras loaded with photographs. Following my own advice, I bought a large photo frame, filled it with our favourite memories of the trip and hung it on the wall. I am left, however, with a pile of pictures which don't have a home. I'm a little torn - if I follow my own advice to the letter, I should really get rid of them, but it seems a waste, seeing as I've only just had them printed. I'm sure I'll be brave enough eventually., but in the meantime, I'm just enjoying having them to look at.
