There are a few principals of songwriting... but it is a very odd question.
Can
you imagine J.S. Bach sitting around because there wasn't a YouTube video on 'Write your
own Cantata'?
If you don't have any ideas we can't give them to you.
Now having said that go and do something useful next year like sign up to FAWM and/or
50/90 and force yourself to write a lot of songs quickly. This gets you over the
self-censorship hurdle. Your first attempts will be rubbish - that is quite usual in any
endeavour.
