Self Management
You are where you are because you acted and decided in ways that resulted in situations and resultant sequence of events.
You are forging this path with every single action of yours. Every major decision and most words and thoughts, play a part!
Manage your decisions, your thoughts, your words; Manage yourself that you may accomplish what you want to.
It’s like anything else! Results are commensurate to the quality of management. And it shouldn’t be that hard, if all you have to manage is yourself, should it!
