I think that you have to be consistent and write regularly. Even if you only answer a few questions or do some hub-hopping, you should be active and participate in as much as you can. Hubpages is not a get rich quick scheme, but with patience and hard work, you will start to see results.
The Learning Center here on Hubpages is a fantastic source of knowledge,tips and advice. By reading this you will gain so much and I rate it as one of the best tutorials that I have ever come across. Read as much as you can and you will gain confidence in yourself and your work.
Take part in the forums as everyone on here is so helpful. It is a great way to make friends while learning. There is a great sense of community on Hubpages and with a little effort, you can be part of this wonderful family.
