So you also need to concentrate on expanding your ability to express what is inside you. If you build up a big tool collection, you need to use them and figure out how they work. Get to know them in and out. In the end, you need to make people feel something using those tools. The reason why I take time to speak about such matters, is because many people get lost in the tools.
Many people leave themselves in the tool box.
And they wonder why they can't write any better. So they usually make the mistake of learning more tools, thinking that if they know enough, then the muse will come back. This is not the case. If you are getting lost in tools, you need to reconnect. You need to live so that you have something to use those tools on.
