Commitment

You need to be committed or addicted to blogging if you are to write a blog regularly. I have successfully stayed away from addictions of any kind be it smoking, alcohol, work... you get the gist? And am happy to remain that way as long as I live.
Commitment? Now that's a different ball game altogether. I have come to realise that I'm a commitment phobic and was surprised when I made the first big commitment of my life by taking the plunge after 3 years of dating a man who was patient enough to let me be when I was scared of committing (I think that's what tipped the scale in his favour...)
I've hardly ever remained committed to anything... I have changed gyms and workouts because I could never stay committed to one, have changed hairstyles every six months for most of my life because I couldn't make up my mind whether long hair or short hair looked better, I have tried all the diets in the book without really completing any one of them and these are just some tiny examples.
So the question keeps coming back to niggle me. Will I be committed enough to write a book, the idea for which is just buzzing around in my mind? Will I be proactive enough to commit myself to writing at least a page everyday?
To tell you the truth, I have my doubts. But then I had doubts about gymming regularly and that's changing... They say people change and I would really like to change, if not for anything else, just to tell the world a story that is just waiting to be told...
