Stars late 409/2378 players left, opinions on this push ?

[greenstack]

Money is 49 players far, just arrived to the table with super short stack, no specific reads.

The last 2 hands I managed to double up going all-in pf from the BB and post-flop from the SB.

Is pushing with 55 ok on this situation ?

Thank you.
