The science is clear. Money buys happiness in a short-term dopamine-hit way. The euphoria is brief. And in the euphoria, one's behavior remains consistent with how they behaved with less money.
So it's likely that both the euphoria and the money won't last.
Humans are subject to the hedonic treadmill, which simply means that good things don't last.
For example, a new car is exciting at first, but it soon becomes just a mode of transportation (that requires maintenance and insurance). A new job brings feeling of accomplishment and progress, positive emotions that wane as the work demands increase.
Most lottery winners end up in the financial position they were in prior to purchasing the winning ticket.
Why? Because sustained happiness takes concerted effort over time, and requires adopting new identities demonstrated in aligned routines and habits. This is very difficult for any person to do without guidance and support.
Thrivable You can help you make happiness easy by building thriving skills. When you're thriving, you come alive and experience the extraordinary...which is more than money can buy.
