Just a few random thoughts (I handle Internet Marketing for roughly 14,000 agents in 7 states, so I do have a little experience...)
Market, Market, Market... and use EVERY tool that your broker gives you!!! If they are paying for it, then it must be working! Take the time to learn it, love it and live it!
Attend webinars when possible. A great company that offers free webinars on Wednesdays is Market Leader... google "market leader power hour". The first half is always generic marketing, prospecting, etc... the 2nd half is how to apply it to their system. No one says you need to listen to the 2nd part. just disconnect. Also, the paperless agent offers some great live webinars each week for free.
Create social media content! Facebook, twitter, Instagram, etc... folks are using this more than ever!
Find a mentor! Many seasoned agents HATE doing open houses... offer to cover an open house for them! You get to keep the leads and you get experience without having your first listing. Most importantly, the senior agent keeps their client happy by having open houses.
