There is no known way that people even have a remote chance of going to another solar system without some gigantic breakthrough in science that is not even being hinted at.
If you are looking for some kind of hope, or freedom from the limitations set on us in life, your better bet is to get into the fields of nutrition-with-a-touch-of-medicine, and longevity (anti-aging). There are a lot of nutritional things around right now that can impart a better life in old age, and maybe even extend life somewhat.
If you are able to sell yourself on the idea of science fiction, there are a lot of sci-fi books around that talk about things like settling other worlds. Why not look at them? Because the idea of really doing it is so far beyond us that it will take life-times to figure out how to do it. And we will all be dead and gone before anybody will ever come close to going to the stars.
