I'm writing this to avoid writing a speech I have to give tomorrow night.
Why do we procrastinate? People procrastinate for different reasons, fear of rejection, fear of change, resentment for "them" your free time away, or a combination of them. Procrastination actually is said by Neil Fiore in his book on the subject to be a psychologically smart strategy in the short term of avoiding the perceived pain of a task or its completion. So, first of all congratulations on being smart!
How to get around it is to schedule some fun after the task, throughout your day and week as a reward for doing it. Sometimes knowing you have fun coming up helps push you get motivated. Making a list and crossing it off helps, too. Some people are overly sensitive to criticism (fear of rejection) and in that case you have to learn to disassociate the feedback you get from product or your actions from your sense of self-worth. You are not being rejected, just what you do or give someone. Take the feedback as an opportunity to improve yourself. Remember too that sometimes we feel good when we are actually doing the task ("This isn't so bad" ) or feel a sense of satisfaction afterward. Get that feeling in your head before you do it and it'll be easier to start.
Now that Ive written this I'm ready to tackle my speech
