Having been doing it for many years now, my advice would be to start slow and take it one thing at time. Slow and steady will definitely help out a lot.
There’s also a lot out there that you can do, so tinker around a bit, read a bit, and ask yourself: what do I want my site to be able to do? Look at others’ sites: what do you like about them enough to want to build on your own site?
Maybe join us for an upcoming event too?
