In our minds resides a demon, it is full of pessimism and fear. It starts seeding our thoughts with why and whatnot, and ends by making us fearful. Most of us have surrendered to it. We have accepted our limitations and have let it rule over us.
There are some days in life when I realise how I got overpowered by this demon. Then I feel blessed and thankful for where I am now. The demon still tries to prey on my thoughts and makes me miserable. It is just that, with all the accumulated past experiences, I am better equipped now to tackle it.
