Since that first (likely RNA) molecule managed the astounding feat of self-replication, every bit of life on earth has had the same overriding long-term goal: survive long enough to reproduce.
In the long run, nothing else matters.
If you don't reproduce, your genes, your pattern, your contributions to the future are all dead, gone, irrelevant, extinct.
Remember Eve, that lone woman from 140,000 BC who's mitochondrial DNA is in every living human? She reproduced successfully, and no other human female from that time did.
Scientists have similarly traced the ancestry of the Y chromosome such that statistically all living human males are descendants of at most a dozen or so men from perhaps 50,000 years ago, or possibly a Y-chromosomal Adam from about 60,000 years ago.
Note that there were many human females--Eve was not alone. She simply is the only one with living descendants. And it was likely not her mitochondrial DNA that conferred some advantage over the others, but rather some gene she carried that protected her against some disease, or allowed her to coexist with some parasite, or perhaps simply made her want to have (or capable of having) more children.
Statistically, your genes must reproduce at least as well as average, and probably better than average, in order for them to stick around for the long term. Note that a continuing 1% reproductive advantage is enough to dominate the overall population in about 70 generations (assuming an unlikely uniform distribution), and to overwhelm 90% of competitive genes in approximately 230 generations (a little over 5,000 years).
Have you noticed that all religions that have remained successful over the long term support the concept of "go forth and multiply?" And that those religions that frown on sex, especially those that promote abstention, rapidly go the way of the dinosaurs?
So, to be a part of humanity's future, you must reproduce.
If you think your genes would improve the human race, you must reproduce. If you are more intelligent than average, you must reproduce. If you are healthier than average, you must reproduce. If your family tends to live long and active lives, you must reproduce. If you are an optimist and believe in the future, please reproduce. If you have less susceptibility to cancer, or heart disease, or Alzheimer's, or any of a myriad other maladies that we succumb to, please reproduce. We need all the good genes we can carry.
Note that this is NOT a call for only "perfect" humans to reproduce. Rather, we need a highly diverse gene pool to improve our ability to survive future threats. And perhaps you have a below average IQ, a family history of heart disease, and you tend to be overweight. But you love children and your family, and are driven to work hard to make the world a better place for our descendants. Please reproduce!
If you think that your genes would make a below average contribution to the future of the human race, then at least seek out a spouse with superior characteristics. It's the combination that counts. We need more good genes, not just the few best genes.
The bottom line: consider your genetic contribution to the future of humanity, and if the balance is positive, you must reproduce. It's your duty to the future.
