Make sure you have both engines selected when you throttle up.
Before rolling, give the plane 9-12 clicks of right rudder trim and 2-3 notches of flaps.
When you do throttle up, do so slowly. 30%, 40%, up to 70% until you reach a speed of about 70mph, then go full power.
As you roll down the strip, apply gradual rudder to compensate and stay straight.
At 120mph begin to rotate.
Take gear up fast, but leave the flaps until you reach about 140mph.

You can take it from there.
