Just remember that the north magnetic pole is somewhere on Ellesmere Island. So from the UK, that's up and left a bit, but from here, it's up and a long way right. Now, your compass always wants to point to the north mag pole, so when you sight along your compass's north arrow, just figure that true north is ~20 degrees left and it's all good.
Or, use a GPS.
