I agree. Cast on and knit. Don't wait for the perfect cast on before you take the next step. Just keep going. At first your stitches could be uneven as you train your muscle memory, but they will even out as you get more experience.
I'd suggest that you cast on, knit some rows, purl some rows, switch back and forth between the two and don't have any specific project in mind. Just work it until it comes automatically.
I'm sure that any knitter in a group would be happy to help you get started.
