Meeting goals at a set time is important. That's the way I see it also. At that time I only dreamd. Only since I have set myself concrete goals, I have made progress. I have set a number of book pages to write a week. It's a great feeling when you see that you've done something. The result does not have to be perfect. The main thing is that you have taken the first step. :)
Since writing my novel and building a routine, it has become easier for me to think creatively.
At the beginning, I also did not know what my story was going to be and now, many months later, I suddenly have ideas. At that time I would never have thought that.
Exactly, start with the first step. It's hard to move a train, but when it starts, it's not going to stop it. It takes much less power to keep up the pace.
