Human Factors
I was originally number 2 to land on Runway 31 following another Cessna in the front. On the right downwind; I was instructed by the Tower to resequence to number 3 following a Diamond Star on the left downwind (just abeam the Tower). I responded that I had the traffic in sight; however; it was the Cessna in front of me; not the Diamond on the left down wind. I beamed the Cessna on final; and turned onto right base. Then; I saw the Diamond Star that was on its left base. Realizing that I made a mistake about the plane that I was supposed to follow (Diamond Star not Cessna); I immediately turned left; following a 270 turn to final. In order to keep more distance with the Diamond Star ahead of me; I then did an S-turn; during which the Tower said 'S-turn approved'. There was still not sufficient separation between me and the Diamond Star in the end. I then was instructed by the Tower to go-around. It was unclear if the Tower or the Diamond Star noticed this near miss incident.
Cessna 152 student pilot reported misidentifying traffic to follow and created a near mid air collision situation with other traffic in the pattern.
