Not knowing what moves to make and feeling lost all the time My tactics and calculation abilities are fairly decent since I practice chess puzzles a lot, but I seem to be lacking in other areas. I always feel uncomfortable in a lot of chess games even though I've honestly played a lot of them by now. As the title suggests I want to gain the confidence and knowledge on what moves to make. I would love to become more adaptable. I love seeing masters being able to play and knowing what to do in any given position and would like to work towards that sort of ability. What should I do?
What you describe is a lack of strategic intuition. Fortunately that can be learnt. All of the following quotes come from Studying chess made easy by GM Soltis.

You need to learn how to spot strategic patterns


  "I only see things quickly if I have seen the position before," GM Yasser Seirawan once said in explaining how he found strong moves so easily.


According to this, developing strategic intuition rests on pattern recognition. When learning tactics, you had:


Theory: e.g. the abstract idea of a pin
Practice: e.g. solving tactics puzzles


This brings me onto...

Learning patterns is about theory and practice

The same thing that was said about tactics can be said for strategic patterns. For example, one pattern might be the exchange sacrifice. It has theory, you can find puzzles, and you can apply it to your games.

Remember that:


  Theory + Practice = Success


Learning patterns is often subliminal

This begs the question, how do I learn these patterns? Well, this is a life-long process.


  Some researchers concluded that the typical grandmaster knows 10,000 patterns (!). Don't worry.
  
  You can become a pretty good player, perhaps even a master, with a much smaller number of positions in your mental 'pattern bank'.


GM Soltis suggests analysing master games, and gave this specific advice:


  Take note of each middlegame move that is awarded an exclamation point. Try to figure out why it's a good move. If you think you understand why, try explaining it in your own words, as if you were teaching a fellow student.
