I think Starillie gave really good advice- and it's one that I really remember to take myself! But looking back, it was always the moments when I was able to look back at drafts and old pieces of writing that I kept, where I found the most inspiration to write. Not necessarily inspiration of what to write, but more like inspiration of belief in my own ability to write, and empowerment to just do it.
Honestly, the only real tip is to just do it! It's rarely what we ever want to hear (trust me, I'm that way!) but the way to get over the blocks often caused by perfectionism is to just do it; regardless of how well we do it, or whether we know 100% what we want to do- but just doing it, however much we can.
I wish you the best of luck!! And if you feel comfortable, I think we would all love to see what you create once you get started!!
