I deeply admired the author who can keep writing and updating his novel regularly, even his/her collections are not increasing at faster rate compare to others. As long you enjoy writing your story, keep going. As long you have one reason to keep going, just keep going! Others factors are just nuisance, they will drag you slow from attaining your goal. Remember "Rome is not built in one day"
If you keep going you might be surprised what's waiting at the end of the rainbow. If you stop in the middle, you will never know...
Take care all.
