How should I be improving? According to the computer analysis on lichess, I seem to make far fewer blunders than my opponents, but I make far more inaccuracies. I assume this generally means I don't have good positional instincts. What can I do to make fewer inaccuracies?

I should probably note that I am playing a lot of blitz. I'm 1500-1600 in 5 min on lichess, and 1700-1800 in ten min. The obvious thing would be to play longer games because obviously I play better in them, but there are only so many hours in a day.
