I was stuck in the perpetual 'hello world' phase for a long time myself

Then I jumped onto a freelance site and bid on a couple jobs

Once you actually get a 'paying' gig and complete it you realize you can do it.

Start with something smallish , a little $20 project - I started with simple scraping stuff (PHP)

I got pretty good with multi-curl / proxies (scraping 1000 pages / sec )

I'm trying to learn game dev / 3d stuff - that's a whole different world LOL
