Youtube: Got Mad that youtube put ure Private Name?

along time i got mad. why google put my private name on my youtube account. but i find how to fix
here the steps:

1.Switch from a Google+ profile identity to a YouTube username (Revert to username)
You can switch back from using a Google+ profile identity to a traditional YouTube username:

2.Make sure you're signed into YouTube, and go to YouTube account settings

3.Click Disconnect channel from Google+, found below your email address.

3.If you had an old YouTube username: You will then be asked to confirm that you want to revert your YouTube Channel to your old username. Click Rename channel and your identity will be reset to your old username. Your old profile photo (if you had one) will be restored as well.

4.If you never had a YouTube-specific username: You will then be able to enter a YouTube username. Follow the instructions and then click Create username. Your identity and Channel URL will be updated to reflect your new username, and your Google+ photo will no longer appear as your YouTube avatar.
