- Don't buy crap
- Don't keep crap (recycle, don't trash them)
- Stop wishing of buying more crap.
Any impression this incredibly wise list of advice could be based on personal experience (and on multiple failures at following them) would be correct. My life changed and the clutter vanished the day I stopped wanting to buy always more stuff and decided to only keep what was... worth keeping aka actually of any use/importance.
Rush less to answer something, maybe?
And for that you won't need to upgrade your mind, nor to pay Musk (or any Musk-wannabe), you just need to take a little more time, say, take a deep breath a couple more times before replying to anything or anyone ;)
Also, don't be afraid to check with an eye doctor your eyes are OK.
