One cannot enable monetization on YouTube instantly after you create a channel. YouTube has changed its policy recently. This means, you can only be able to monetize once you reach 10K views. You can only create a custom URL channel once you hit 1000 Subscribers.
Even if one have an approved Adsense account, one cannot enable monetization. Once you hit 10K views, YouTube itself will invite you for Partnership program. You can apply for new Adsense account or sing in and enable monitiezation once you're eligible.
Create a channel, upload a banner and upload videos and share them on Google Plus and twitter. Because most of the views and subscribers comes from outside YouTube.
Also, if your video is longer than 15 minutes, YouTube will surely review your channel before you hit 10 k views. From my personal experience my channel got approved after 6k views.
