It is much the same in business - if your are a procrastinator then you should start doing the jobs you don't like first. Get them done. Get them out the way. Get them behind you and then you can proceed and have an awesome day, not only doing the things you like but also having a sense of freedom and achievement.
Eat that frog by Brian Tracy sums things up really well. So, if you are a procrastinator pop to www.actnow.ie and EAT THAT FROG.
