Being a writer is a strange and unusual compulsion.
On the other hand it makes life very interesting.
I don’t think there are many other occupations which begin the day with research into diving equipment, loiter around the methods of disposing of a body, and end with a copy piece about Madeira cake.
The hours are often long and the pay is poor. I recommend that for the first few years of throwing words at the world you forget all about working out your hourly rate. On the other hand there is something to be said for beginning the day in joy and completing it in satisfaction. You might not be rich as a writer but if writing is your compulsion then as long as you are allowed to wallow in the words you stand a good chance of being happy.
