What is it you want?
Where are you now?
What is holding you back?
When are you going to do something about it?
Any dream, desire or want starts as an idea. The thing people do to achieve big and small dreams and goals is simple: they break it down into actions that can be done each day. Then they schedule those events.
Life happens in time-space continuum and the only way to achieve whatever is that you want to achieve is to be working to make things happen. Break the big dream into projects and projects into smaller goals. Then set actions for each goal and schedule those actions for the next days, and weeks.
