Approach developing your game like you want to build a house. You may choose an apartment or a mansion... the more beautiful the structure you want to create, the more detail must be paid to the details, the location, architect, material, you get it... Build each room at a time. Make each room as well as you want it to be.
For example, fix your backswing, focus on making it perfect. Allocate it 5 hours of quality work before you proceed to the next 'wing'. This will inevitably slow down the process but it will allow for deep learning. Remember if you want to play until you are 80, 2 years dedicated to building a foundation can be a worthy investment. Also, your game will be the talking point of your friends.:)
The Strokes build on one part to another, if you have a faulty swing, it will impact your swing at the point of contact which will reduce your overall quality of the shot.
