When you have only a vague notion of what you want to accomplish, it's helpful to stand back and visualize. You need to clarify exactly what it is you want to accomplish.
Clarify what you want to accomplish
When visualizing ask yourself these questions.
- Where are you?
- Who are you with?
- What are you looking at?
- How far off in the future are you thinking about?
- Why do other people like it?
- How do you feel about it?
This will be done when what is true?
Once you have visualized it, you should have a better notion of what your goal is.
Now the question is how do you get there from here? What is the sensible direction?
There are a lot of ways you can find out.
Get feedback from others
Ask people around you. They will give you some feedback to start. Share what you want to accomplish and chances are very good that they will have some ideas about it that you have not thought about. Take advantage of the fact that everyone sees things differently. The more people you ask the better. Take good notes and listen carefully when they tell you. Be sure to ask questions about what they are telling you.
Find out how its been done before
Look to history. History will show you your initial motivation and feedback. Whatever it is you are doing, others have probably tried it before. Find out who those people are and get to know them. How did they accomplish what they did, why did they try in the first place? How did they fail at first? What are the caveats and shortcomings you need to be aware of. (This is where your improvements will propel you forward) Look for patterns of behavior you can use.
I do want to say that you want to do this as fast as you can. Don't get bogged down in research. Once you have gathered up ideas about how to accomplish your goal you can begin organizing these ideas and get some notion of what you need to do and in what order.
Be BOLD and do it
Now is the time to perform. Now is the time to be bold. About that fear of getting stuck indefinitely? LOSE IT. You have to embrace failure. Look to sports as a model. In football/soccer every kick is an attempt to score a goal. Most miss, but someone eventually kicks the ball and scores. Thomas Edison tried many times to invent the light bulb and failed until finally he succeeded.
If you try nothing you accomplish exactly that, nothing. If you try and fail you have discovered something new about what you can do differently. In time you will discover how you can do it and even better, how to do it well.
