Raising self awareness on things like this is good. HOWEVER, be careful not to throw away all commitments because they don’t make you happy right away.
Buying a house as a couple is expensive. Having children is even more expensive. The steady stream of “stuff” that it takes to do this isn’t what makes people “happy” directly. It is a vehicle to use so that you can share with others.
For example, at age 25 I got a pilot’s license. I flew around by myself for a few dozen hours and realized that although I was still enthusiastic, I was missing something big.
So I took friends with me on day trips. I showed their kids (or nieces and nephews) the sheer joys of flying an airplane, and introduced them to the science and engineering of all the fun, obscure bits and pieces of the airplane. Owning and flying an airplane is expensive and it’s not much fun. Taking family and friends places they’d never see otherwise is priceless.
It’s not about the stuff. If stuff makes you happy, you’re one very shallow person. It’s about sharing yourself and your time with others.
