Making the decision (and yes, it’s a decision) that there are not enough resources or that using them in a certain way is irresponsible is a perception. It is not a reality.
There are as many opinions of what constitutes wise uses of resources (money, for example) as there are resources to be used. Any and all perceptions are biased.
Reduce your doubleminded thinking and your fear of making the wrong decision. And you will make way for the joy of going after and getting exactly what you want.
