“Think lightly of yourself and deeply of the world.”
“Do not, under any circumstances, depend on a partial feeling.”
“Do not seek pleasure for its own sake.”
“Accept everything just the way it is.”
If you are a writer, then you should publish. You should share the words and thoughts you produce; be it for entertainment or informative.
It makes no difference to your writing and publishing journey what others are doing. Stop comparing your road to theirs. You have decades of experiences they do not, and vice versa, therefore comparison is pointless.
Your greatest strength and weakness, lies in your passion. It can be used to fuel great creations with reckless abandon for everything else in your life. Or it can result in wasted years on trivial activities that only supply momentary enjoyment; heroine.
It is normal to feel anger, but it offers little value to your life. Acknowledge its existence and use it as fuel to change.
Want to be a writer? Then be a voracious reader. How else are you going to learn what has come before you, and how best to accomplish the task you have set for yourself?
Stop focusing on the big picture goal that you are working towards. That is there to set your path.
