You still have a lot to see yet. Tons. You’ll be hundreds of hours in before build fatigue Ultrazen mentions rears its head. Go watch the ‘Build of the Week’ series on GGG’s YT channel. There are dozens and dozens of amazing, weird and wonderful builds you can experiment with - PoE smashes it for build diversity, even if they do all have '200% life nodes on the tree" in common.
You’re earning repec points as you go, so have freedom to back up a little and fill gaps. As noted above, the biggest newbie mistake in PoE is not taking enough life nodes on the skill tree. Your gems and links can scale your damage (with some modest boosts from the tree), but your life pool (or ES pool) needs the love. Also life and resistances on gear are usually good options until you are looking to target specific affixes that may benefit your build and you can afford to drop some mitigation.
Check out some of the offline tools - Path of Building or POESkillTree. Plan out some toons for fun. Plan for around a 60-70 skill point allocation as most builds should be able to get that far before hitting any serious hurdles. Plan for a min 170%+ in life nodes. Fair warning, something like PoB can be quite in-depth and rather opaque without knowledge of the game systems, but it can be handy to see the effect different skill gem combos may have.
Mostly though, you are just experiencing the learning portion of the game, it’s totally normal to be dying a lot until you start to grok how to build towards the right balance of mitigation and damage on the skill tree. Heck I played on and off for years before advancing a toon beyond about 40, but that was before a bunch of changes were made to the early leveling experience (links kick in earlier now, most gems are readily available at the vendors, etc).
I talked about this in the D3 thread, but PoE does not hand your build to you on a silver platter of unlocked skill categories - here’s a damage skill, now an AoE skill, here’s a defence skill, now a mobility skill, etc. Instead it give you the freedom to do what you want, mostly when you want, with a staggering amount of content thrown at you. Sometimes it takes a few deaths to realise you are missing something that another game would have thrown at you as part of the progression. Then it takes some experimentation to come grips with the array of skill gems and what they can offer.
I kind of want to say you should persevere until closer to 60, to see how more links can begin to affect your gem choices, or force you to throw a bit of currency at a nice bit of gear to get the right colour sockets, or see some of the gems that only become available in later acts. But you know what? It’s just as valid to go back and start a new toon and build on the knowledge you have gained with a fresh character. Whatever keeps your interest up until the game systems begin to come together.
