There are books like "Think like a Grandmaster" that examine the thinking process and attempt to give you a method for picking and evaluating candidate moves.
Not considering good moves

You don't have to find a move that wins immediately. You have to find a move that just doesn't lose immediately.
If you were playing your opponent's position, what move would annoy you the most?

That's a very interesting thought that I will keep in mind!

Thanks a lot!
I will definitly go over the opening errors. It's not just good to exploit them, but it will also point me to the errors I should try to avoid.

Here's another great CM course that I had forgotten about. Not that difficult and makes you think about what your opponent has in mind. I tend to spend most of my time on CM reviewing GM Wolff's tactical courses since I think tactics provide the most "bang for your buck", but there is an embarassment of riches available. Rare that I envy youth, but were I not a doddering old man, I think the CM courses alone could make me a pretty good player.
When i analyse my games, I often notice that I often make a move that gives my opponent an advantage.
When I look at the possible good moves, proposed by the engine, I try to analyse why they are good moves. I don't look at the sequence of moves, just the first one.
Often I understand why and can clearly see why my move was bad.
I ask myself why I didn't see that move because if I concidered such a move, I have the capabilities of seeing the advantage however I did not concider it.
Are there any patterns that can help me consider the best moves because it's a bit frustrating to see that good moves are out there but I don't see them.
