A wery good question. Where to start from?

Here are some ideas for you:

1. Connect with your dream.
   Set aside some time to dream your dream.

2. Come back and settle on one or two dreams that you can and will pursue. Don't come up with too many, if you want to have a full accomplishment

3. Decide that you will do it.
   This is very important. Many people never come back to real world to take a decision. They remain prisoners of their dream.

4. Tell others that you are going to do it.
   That means you assume the responsibility of doing.

5. Develop a step-by-step plan.
   It is absolutely essential. You must sit down and write out a few things:

6. Set up a timeline. How long will it take to the end?

7. Develop action steps.
   Point-by-point what you will do and when you will do them. "Action may not always bring happiness; but there is no happiness without action" -- Benjamin Disraelli

8. Assign resources you will need to draw from.
   Who will need to be involved for help or advice?

9. Develop an evaluation tool.
   You need to evaluate from time to time whether you are progressing or not.

10. A celebration.
    Plan what you will do to celebrate. Make it big!
