Some good ways:
Step 1 - Grabbing the link
Go on a YouTube Video of Your's and Grab its youtu.be link (This is now the official sharing link by YouTube) by clicking the share button below your video
Step 2 - Sharing on Facebook
Share the link on Your Facebook Wall and Chat all your online friend to watch it just to get the view (If you have 20 people online, think of getting those 20 views, it will help you a lot)
Also pleasing them to like your post will make it appear on the top news on facebook and then it will get more attention
Step 2.1 - Beg your facebook friends
Begging your friends to post your video on their wall will also generate you some good views =D Spread it as much as you can, with their help you can succeed!
Step 3 - Post a bulletin
Log in on YouTube, and Go on your channel page, on the top left, next to the channel settings, themes, modules etc. there is the Post Bulletin Button, Click it and Share the youtu.be link there and in the message box, enter a text saying "Please watch this video and help me get views" or something similar, if your friends/subs are generous they will most probably click your video and you will get some extra views
Step 4 - Post the youtu.be link on Forums
If you post a direct youtu.be link and don't embed it on a forum/website, i think it gets more views, because actually users watch it on the official youtube page and it counts views more efficiently, so try putting a direct link for example from forums, and when they click it from the forum or open it in a new tab, at the insight views it will say that views came from FORUM URL and this is going to help you a lot at the views, especially if the forum has many members, a good way to make the best out of this idea, is to go on the "OFF TOPIC" section of big forums and post your youtu.be links there!!
Step 5 - Embed your video on your site blog
If you get some serious views on your blog this is also going to help you get some views on youtube, for example i posted one song i made on my blog and got like 25 views from it
