After my partner and finished our OW course we just went diving. We’re lucky to live somewhere (Sydney, Australia) with lots of accessible shore dives with pretty good online resources about them.
Some dives we did with more experienced friends, but we also just went and got wet.
We also did a bunch of DM guided boat dives, but our 7th dive (ie. 3 after OW) was a boat dive where we went off by ourselves without a DM.
One thing I’ve learnt is to learn from the more experienced divers around you by watching, but until you’re diving without a net (DM) you don’t learn to navigate, or plan and manage a dive.
So yes, go dive, go dive often.
