The 25-year-old was beaten by Novak Djokovic in the Australian Open final in January after winning his first Grand Slam title at Flushing Meadows last August.
The British No1 is aiming to improve on second-round defeats in the past two years at Indian Wells and reach the final for the first time since losing to Rafael Nadal in 2009.
“Preparation and consistency are key for me this year and I’m going into every tournament I play with the aim of winning it,” said Murray. “I’m in a good place right now.”
Murray also claimed that drew a lot of positives from his five-set defeat by Djokovic in last year’s Australian Open semi-finals.
“I learned a lot in the Australian Open last year,” added Murray.
“I had a great match with Djokovic, it was 7-5 in the fifth set, that was five hours nearly. I lost but I had chances and it came down to the last few points. I gained a lot of belief from that.
“I knew that I could last physically with him and I also dictated long periods of the match. It was nice to come off the court in a big match not really having any regrets, and I think that changed a few things.”
