Sometimes new stuff can solve your problem. Most of the time it wont. Most of the time it will go the way of the New Year's resolution treadmill that collects dust in the garage.
The more stuff you have, the more anxiety you'll feel. I'm sure there's science to back that statement up but I'll stand by it either way. Just head into nature unplugged and you'll see that it's true.
Minimalism is about getting rid of unnecessary stuff. Clearing the clutter calms the anxiety.
But then you'll be tempted to solve new problems with more stuff and the cycle continues. You'll even convince yourself that you can only clear the clutter and achieve minimalism after buying that stuff.
If we're to have any hope at achieving sustainable minimalism, we must master the skill of resourcefulness. Resourcefulness employing creativity and ingenuity to make use of the things you already have.
With just the few things we need being fully employed, we're free to whistle while we work and enjoy the wide open spaces of life.
