Don't Buy Your Way to Better Habits
A while back, I had a goal to start waking up earlier every morning. To motivate myself, I decided to buy a fancy new Bluetooth alarm clock to wake me up at 6:00 a.m. New habit, new toy.
Obviously, this didn't solve my problem. In fact, it was a distraction (and a waste of money).
I didn't think about it while I was buying it, but I unwittingly tried to buy my way to a better habit. Rather than focus on what mattered, the discipline, I focused on something much easier: buying shit.
This is a common issue with diet and exercise, too. You want to get in better shape, but instead of slapping on some running shoes and hitting the block, you buy a gym membership you never use or a treadmill that collects dust in the garage. (It's not just habits, people do this with major life decisions, too. )
Of course, there are some exceptions to the rule. Buying something to support your goal isn't a bad thing. The key is to make sure the purchase supports your goal rather than replaces the work it takes to get there.
