Too often we set our sights on the end result and ignore the next steps. When the end result is far away, we can feel overwhelmed and simply never get started.
I think this is particularly true when we want to learn new things. We think it will take so long to learn and acquire new skills, so we simply stop learning new things or taking on new challenges.
When the end result is far away, stop trying to look at it. Focus on taking some kind of step toward your desired result. Just one step each day. If you focus on taking one step every day you will reach that far-off result that had looked so far away.
The years of work that scare you away from getting started are going to go by whether you use them to work toward that goal or not. Might as well work toward the big goal you have.
