Nothing.

My greatest fear is making a mistake that I cannot fix. It is also being alone for the rest of my life, and being forgotten - being irrelevant; and not doing anything substantial - significant - with my life.

So, to battle this fear, I rationalise all my choices until I either a) not do anything at all, or b) convince myself that the less ideal decision was made as part of a necessary growth process. Everything gives me an opportunity to learn something new, and so there are no mistakes. Only lessons. 

I know that the universe and fate and life is one massive game of dominoes. I know that everything that is, is as a result of something that happened before. I know that, truly, there are no mistakes in life, and there is no growth without pain, or experience, and that, for example, one failed class results in increased motivation not to fail the next one. I know that arrogance is believing you are above certain circumstances, and that only errors knock us down to earth. I know that I would not be here today, if it weren't for decisions I took a few years ago. I know I have grown, and that I am better, and that the future is clearer to me than it has ever been. I know that. But I am alone today. 

I guess, I have learnt that I can do something significant with my life, and I am on that path. But I am on that path alone, and that fear is stronger than it has been in a while. Because, what if I have made a mistake? I don't know what to do. So I am not doing anything.
