The key to space travel isn't moving through space faster, it's slowing our own aging process down to such a grinding halt that we can survive for thousands of years, if not indefinitely.
A one thousand year journey to the next star system may seem like an impossible to wrap your head around concept, but as you get older your perception of time does speed up ever slightly.
If you were immortal, it would eventually get to the point that 1,000 years feels more like 100 years. 10,000 years feels like 1,000. 100,000 feels like 10,000. And so on.
