Do many Sun Squares (priority), then Jupiter and Venus Squares (secondarily). Good things is there are many good dates for Squares until the end of the year,
check here. I wouldn't overlap them but it seems you can do many squares one after the other this year.
Become really good at a skill that is deemed worthy in the market and makes you feel useful, like a specialization. On that a Mercury Square could help (if you look for something very intelectual like IT based or related to medical fields). I would save it for next year (the square not the education or working) as it's a very long square and would spam Sun and Jupiter squares now.
