Last year I did finish quite a few projects that were on the resolution list 2012 so I am pleased with that and I hope to do the same this year. Setting a goal is the key, either with quantity or time as the measure. Time is usually my meter - finding that it defines the boundary for me and gives me a realistic doable objective. Completed projects clear the mind [and workspace] of mental and physical clutter - so that it can be filled up again! This is what frequently happens with me - there is always a new project in my head waiting to emerge.
What are your goals, is the goal achievable, is there a finish line? To help, divide your intentions into smaller parts like chapters in a book. The book consists of pages that make up chapters that make up the book. Do you see what I'm getting at? Try it and see how you do.
