You need to learn more in order to get better thoughts. Learning comes from everywhere, not only by reading books.
Your experience is also a type of learning.
The experiences that you have will most of the time be unique because only you know about your circumstances.
But, sometimes it is better to learn from other’s mistakes, this can be done through content consumption.
It is difficult to blog every single day. Because, it forces me to find experiences in a day, and write it in a few sentences. So this in turn forces me to learn more.
