Hi,
There have been too many of these "no motivation/should I quit YouTube" threads being created recently, therefore I am locking this thread.
If you no longer have your heart in making YouTube videos, then it's best to focus your energy on more exciting and productive things. Life is too short to spend it working on something you do not enjoy.
For general channel and technique advice on how to improve your content, I recommend checking out the strategy and technique forum:
http://yttalk.com/forums/strategies-technique-advice.14/
I also recommend reading through the YouTube articles and tutorials forum:
http://yttalk.com/forums/youtube-tutorials-articles-resources.10/
That forum is filled with advice from many successful YouTubers, and is very motivational to read through.
For channel-specific advice and feedback, I recommend posting a thread in the reviews and channel feedback forum:

Threads posted in the channel feedback forum will be reviewed by moderators, so please make sure to read through the rules before creating a thread.
