This is an interesting question and depends, I think, on why you want more and what it is exactly that you want.
Humans are naturally goal striving animals. We’ve been striving for goals for the last few thousand years. Why would that change now?
It’s interesting being involved in coaching and seeing the amount of people who are life coaches or similar in the “industry” now. (I think the industry is “Self Help” or similar). I think this is based on our natural desire to help others AND to strive for more.
If you want more so you can have more (stuff), I think you’ve missed the point.
If you want more so you can be more, then please, be selfish.
We need more people who want to be more.
