Sometimes you have to give yourself a pep-talk. This positive form of self-talk will help you self-motivate.

Use the same techniques you use when giving an employee pep-talk. 

Step 1 - Empathy   

• Acknowledge your emotions. They're real.
• Don't try to change how you feel. Accept your emotions.
• It's okay to be anxious, worried or frustrated.
• Take a deep breath. Think of yourself in the 3rd person. 
• Consider any thinking traps.  
• Avoid fixating on conceptual threats. 

Step 2 - Direction 

• Stay in the 3rd person - what should "he"/"she" (vs. "I") be doing today?
• Focus - what would make today a success? Prioritize "his"/"her" (your) immediate "to-do's". 
• Think small - what baby steps are immediately available to "him"/"her"?
• Take precautions - what can "he"/"she" do to eliminate risks? 
• Start small - what's the easiest way to start? 

Step 3 - Motivation (Reason) 

• How do accomplishments make you feel? If you feel good, there's a reason to act!
• How does procrastination make you feel? If you feel bad, there's a reason to act!
• How might you benefit from accomplishing this task? Those are reasons, too!
