This statement makes sense when I think about the reasons I don't start things ( or the reasons I don't finish things). To start things you have to be curious enough to want to see what will happen and committed enough to follow through. Somewhere in between those two statements lies a trail of objections, self doubts, all kinds of fears; some you know and some lurking in the background whispering reasons not to start, the busyness of everyday life, and a myriad of easy to respond to distractions instead of starting something you have always wanted to do.
Sometimes starting something requires that a person change how they do things, how they look at things, how they feel about themselves. Sometimes a person is already judging the finished product or desired outcome in a light that prevents one from even considering beginning. It becomes another fleeting idea that you might do someday off in the future when you retire or when you win a million or when the kids have left home. And so you simply don't start. Sometimes we have so many projects to consider that this keeps us from starting something because it is hard to choose.
You can always learn from something even when you don't start a project and find yourself wondering why? Start asking yourself questions; what do I really want to do, how do I make this priority, where can I get the material, where can I find a teacher, etc. Keep asking questions and the answers and the resources will arrive.
When it comes down to it what is required is a strong connection to the project to make that leap and get started. We need to connect to the joy of the journey, embrace the experience and dig in. Simply by taking the first steps, silencing your critic and walking the path you can embrace the experience, embrace what learning you can get from it and enjoy the ride.
