1. Learn to say "NO": Its never easy to say a "no" to someone. But having too many commitments to honour can be a serious drag on your time and ultimately your productivity. The key here is to prioritize and say to 'yes' to only those opportunities that you really care for and are passionate about.
4. Be Disciplined: Discipline is the chose between what you want 'now' and what you want 'most' in your life. If your ultimate aim in life is to become a successful blogger, make the 'right choices' now.
10. Don't Procrastinate. Start doing. If you have a blog post idea, start by jotting down the key points NOW.
12. Exercise and lead a healthy lifestyle. A active mind and body can help you work wonders.
The best way is to devote your entire attention to the task at hand. Complete one task and then move on to the next. Ultimately it comes down to your will power and sense of discipline. Its all about getting your priorities right.
