It won't feel like 40 years in the space craft. Special relativity makes the trip much shorter on board than on earth. So it's plausible for humans to make a trip to another solar system within a reasonable amount of time (on the ship) without going the speed of light.
I'm not sure you are right about relativity in this situation.
For the space traveler is would indeed feel like 40 years traveling to that star.
For an observer on earth it would be many many years (100s?) before they saw you arrive at the star.
Atleast thats how I understand it

Does less time pass if you are going that speed, in relation to an observer from Earth? As in, if a person could experience light speed travel, the trip would seen instantaneous, whereas one oberving this traveler would still experience the light years encurred?
So basically what you are saying is whenever I get laid I travel at light speed?
