Procrastination prolongs the journey. It allows one to stay stuck and not move forward.
Let's look at it from a completely dualistic approach. Let's make the logical mind happy for a moment.
You FEEL you should do this. But your mind is saying "not now, put it off, do it later" and excuse upon excuse as to why or how that thing cannot be accomplished. Fear may be obvious or not, but resistance is usually obvious if we pay attention.
Your SOUL messages come through your heart. You FEEL them. You get epiphanies to support them as your SOUL speaking to you. Those moments appear brilliant as your Soul has access to everything you need to know, why your logical mind only has a part of what it "thinks" you need. It also serves the purpose of playing out the game of duality and will "talk" you out of it as long as you allow.
Think of every time you finally did what you avoided for so long. Do you remember the freeing feeling "after" it was completed? Sorting through this, cleaning that, getting rid of these, dealing with whatever kept you stuck... once you stepped into it and did it, all that "trepidation" fell away. All of those created chaotic moments just disappeared. That is because the thinking/logical/rational mind will find every reason not to do what one FEELS they should do. It IS it's purpose to create lessons for us to learn from by giving us hardships to overcome and heal. So what if you could avoid a hardship and step into your Soul's purpose much quicker and with greater ease. Would you choose to just go ahead and step into that "thing" you are avoiding a bit quicker. Imagine all that you can bypass if you CHOOSE to listen to your heart.
Remove can't, won't, don't, shouldn't, couldn't, but & no from your mind and vocabulary; replace with yes, ok, can, sure and thank you.
So the next time you hear yourself wanting to avoid, procrastinate or delay. See what you are avoiding. You might get to your next purpose much quicker! And if it has ANYTHING to do with creativity, DO IT!
