It is not an easy task to overcome stagnation, because you need to beat yourself. Like a game of chess, you need to outplay the stagnation and move forward with the best move possible.

What I like to do when I get stuck or when I don't know the answer to the question
"What am I going to do with my life?"
I isolate myself, stopping every possible distraction around me. Then I close my eyes and start asking myself questions like:
"Do I like what I work right now"
"What do I want to do with my life"
Then you come up with ideas and you will definitely know when you find the right answer. That is how I started writing in the first place.

The first thing to do when you are stuck in life is to realise you are stuck. The isolation practice I do that I mentioned above helps me discover and realise everything around me on a deeper level. You then should start working on what you want. Even if it sounds selfish to work on you just remember that you first need to work on you and then spread and help others. It always starts with selfishness.

That is what I do. Excellent post.
