Trying to start something new can seem overwhelming. Maybe the task is complicated and complex. There are all sorts of items you have to plan out and consider to avoid making the wrong decision. My recommendation is to start simple - pick a task that will move you closer to your goal and accomplish that task. When it is complete, move to the next task that needs to be completed. Slowly, step-by-step you will get closer to accomplishing your goal.
I needed to start this blog. As I was working through everything, I started trying to put together the perfect first post and realized I wasn't even taking my own advice. So I scrapped my original blog post (maybe I'll use some of the thoughts another time) and created this very short and simple post.
Having simple, attainable tasks that you can accomplish will give you a sense of progress and keep you motivated as you move closer to your goals.
