My first advice would be to make a commitment to yourself! Marketing online takes time to gain traction and so it's so important to set small baby step goals for yourself each and every day and DO NOT GIVE UP!
No one is an overnight success online... even though it may appear that way.
Pick one or two online tools that you think suits you, whether it be blogging, Twitter, Facebook, etc... and learn everything you can about each one. It's easy to get overwhelmed with everything out there. You can waste a phenomenal amount of money trying to get information on what's working on today's internet - and it is constantly changing.
You can be super successful marketing your product online, but it takes persistence and commitment - that is why people fail often, they give up way too soon!
