transistors - Normally ON Switch using N-CH MOSFET and pull-up resistor

I am learning about electronics and am having a hard time finding a normally closed (i.e. on) switch using transistors and FETs. Am I violating any rules with the circuit below which is using an enhancement mode N-channel MOSFET with an NPN driver transistor? Can I simply pull up the FET's gate high with R1 to keep the switch on (by default)?
