            session()->flash('success_message', 'Post was added successfully!');

            $this->reset();

            return redirect()->route('posts.index');
        }

        // abort(Response::HTTP_FORBIDDEN);
    }

    public function render()
    {
        return view('livewire.post-create');
    }
}

There are two thing here to note - you don't initialize $this->post and you don't have the proper validation. You need to check for post.title and post.body, and you also need to display the actual errors.

<?php

namespace App\Http\Livewire;

use App\Models\Post;
use Livewire\Component;

class PostCreate extends Component
{
    public $post;
    public $points = 10;
    public $energy = 1;

    public function mount()
    {
        $this->post = new Post;
        $this->post->user_id = auth()->id();
    }

    public function increment()
    {
        $this->points++;
    }

    protected $rules = [
        // 'category' => 'required|integer|exists:categories,id',
        'post.title' => 'required|min:4',
        'post.body' => 'required|min:4',
    ];

    public function createPost()
    {
        if (auth()->check()) {
            $this->validate();

            $post = $this->post->save();

            auth()
                ->user()
                ->increment('points', 10);

            session()->flash('success_message', 'Post was added successfully!');

            $this->reset();

            return redirect()->route('posts.index');
        }

        // abort(Response::HTTP_FORBIDDEN);
    }

    public function render()
    {
        return view('livewire.post-create');
    }
}

To display the errors from validation, you can add the following snippet in your blade-file,

@if ($errors->any())
    <ul>
    @foreach ($errors->all() as $error)
        <li>{{ $error }}</li>
    @endforeach
    </ul>
@endif
