Human Factors
Landing at SMO runway 21; had fast approach; used approximately 2800 feet of runway. I was looking for last taxiway and missed it A1; taxiway was much narrower than I expected. I was advised by tower I was on unusable portion of runway that had been recently shortened and caution equipment and obstructions. I did not see a way to safely get back to taxiway due to taxi light spacing and other equipment on ground. Asked to go back to taxiway A1; from unusable portion to taxiway; I then taxied back to taxiway then to taxi destination. Slowing down well before approach would avoid this situation; or requesting go around; which I could have done an executed an approach at normal speed making prior taxiways easily assessable.
