Your best project ideas are going to come to you in day-to-day life, like the time my roommates started complaining that the laundry machine in our basement was always being used. A couple days later, a simple web app was hacked together that displays the washing machine status, and let's anyone "claim" the machine. I did that project when I was in college, and I probably knew way less about web servers and Node than you. I just Googled the first thing I wanted to do "make a website", struggled for a bit figuring out DNS and hosting for the first time, and then put up a test page. Seeing a page show up on the internet at yourwebsite.com for the first time is a pretty magical thing, and the rest was history.

In general, what you need is activation energy - that initial bump to get the project or idea started. After that, you need to practice maintaining the motivation to complete the project you started.

Asking the HN community was an excellent way to start. Good luck!
