You may have been wondering if you should start a blog to share your ideas, hobbies, knowledge or an interest in a particular area of industry/research. To you I would answer with a resounding "Yes!" - Why? Because if you can discipline yourself to writing regular interesting blog entries then a whole world of opportunities will open up for you.
Firstly, you will start taking a greater interest in your chosen field and begin to learn more on your subject. You'll also find that the practice of writing not only gives you pleasure but can become financially rewarding as you may now be invited to: write other articles, reviews and books; with a blog comes a certain legitimacy and you may now be able to charge for consultancy or be invited to talk on your subject. Your thinking will become clearer and you will build your confidence and challenge yourself.
