"Full Power, prevent excessive pitch, roll and yaw, drag flap up(i.e. flap from 30 to 20),check you have a +ve rate of climb (and clear of terrain)then flap to 10" and so on.
However, flap 30 is not going to kill you in the climb if it is left down. The old Cessna 172 used to have 40, which really needed to be watched when you applied go - around power at low IAS, it also gave mega drag and needed to be retracted asap!
