Simultaneity and frames

i recently posted a question (light and time) someone told me to look into loss of simultanety...
according to what i read the speed of light can be judged by someone or things frame of reference.(if im traveling at .999 the speed of light the light in front of me and coming from behind me are still both passing me at 186000 mps) so unless i look at dialation of light (red or blue shift of stars) i am not moving.. i am in my frame of reference.... if i release a pulse of light it takes off at the same speed in all directions... so within my frame cant i continue to accelerate????? matematicaly passing the speed of light compared to someone elses frame of reference?? even though them looking at my "clock" as being slow makeing it seem as if im still traveling under the speed of light to their frame??

 

i have read janus' post on rules.. i just want to state that i am not here to chalange any existing theories.. i am here to expand my understanding of the universe by use of argument and thought experiment.. i am a high school dropout.. all my knowledge has come from the science channel. therefor i know its lacking . my questions are from many hours of thought and interest. some of them i have had for many years. i thank you all for taking time to help me understand.. and if i ask something that cant be answered from a book then try to understand it with me.. maybe the question or theory is already there just worded differently..

 

ok so given this. If something is 10 lightyears away. Could i accelerate to the point where in my frame it only takes 5 years to get there?? This would slow my clock. Probably to the point where from someone else's frame they seen me travel for 30 years before i arrived. Is this how it works?
