In the course of my journey in life and on accounts of bagging a number of regrets along, this is something coming from a bit of experience. It is simple things such as swimming from example or pursuing some other hobby. There is the fear of failing at it. In someone's life it is the fear of rejection from a beloved, the fear of being called a fool in a room full of presumably intelligent people, that you think know more than you, the fear of applying for a job or a scholarship pondering unnecessarily on the negative.
Why? Because in all the cases there is the fear of rejection, failing, losing but we hardly realize that it is always worth a shot. It is better than trying our luck at something than regretting it later just because we didnt try it at all.
One of my fears may seem ridiculous but it has been so. I have had this love for calligraphy for a long time. I have been a good sketcher and thought that it wont be too hard to get good at this art form. Its been 3 years since I have randomly tried to work on certain calligraphy pieces, bought the pens and books to learn from but never finished anything. Somehow a tiny bit of fear lurked somewhere whispering ' what if I hold the pen and start writing and fail to create a beautiful piece'. The fear of failing in my own eyes, of realising that I cannot get better at it always held me back.
Little do we think that its worth a try. Unless we try, we wont know and when we try, there would be one less regret. At least we would have given it a shot.
