Wait till you go past 40 and they start calling you "sir" at Starbucks :) There are two sources of meaning in life: being self-focused and trying to achieve your own goals (like going to Mars) OR being others-focused and trying to achieve something good for them (like parenting kids or helping a group who can't help themselves like curing a disease, fostering animals, etc) The former tends to start feeling hollow after 30 although some people never lose that kind of drive (and nothing wrong with that) Living for something beyond yourself is a good way to spend a life and brings much joy you can't get or buy any other way. The two are very similar in the end, they differ by how you define the success criteria.
