Sania's partnership with Czech Republic's Barbara Strycova came to an end a few weeks ago due to a "difference in priorities".
Her partnership with Strycova lasted 10 tournaments. The Indian had earlier parted ways with Swiss ace Martina Hingis.
"I have had a solid, solid start to the year. I have already played a Grand Slam final (mixed doubles at Australian Open), a title (in Brisbane), some finals (Miami, Sydney) and a bunch of semifinals. I am very critical of myself and always feel I can do better, no matter what and possibly win more titles," Mirza told PTI.
"We have committed till Wimbledon for sure and probably for the rest of the season," she said when asked about her plan for the future.

Mirza, who started the year as the No.1 ranked player, has slipped to seventh after having claimed just one title so far in 2017. She will be playing in Madrid with Shvedova and expects a change in fortunes.
To a query as to why she ended the partnership with Strycova, Mirza said, "We had different priorities. Barbara is very good in singles and when she has a deep run in both singles and doubles at a tournament it becomes tough.
"She has to play eight-nine matches week after week and was getting very tired. We were not able to win for certain reasons. Priorities were different and we felt it was time for a mutual break."
"It was the toughest decision at that time. In hindsight it was the best decision I could have taken. I have enjoyed success in doubles and have been undisputed No.1 for two years."
The 30-year-old, who was in the city to inaugurate an exhibition, organised by her sister Anam, said she hardly cares for criticism but personal attacks on social media are irksome.
"There is a lot of negativity around. That is one downside of social media though there are a lot of upsides. You learn to deal with criticism over a period of time. But, personal abuse should be avoided," she said.
