What would you have done differently?

Hi all,

I am 22 and planning to take the LSAT in a couple of years. I was wondering: If you had the opportunity to go back to age 22, and knowing that you would be taking the lsat later, what are some useful habits you would have cultivated to give you an edge at the lsat? would you have read more, read more difficult stuff, practiced grammar in some way,...

Many thanks!
