Learn something new every day.

Read books every day.
Put aside at least 30 minutes daily for reading or listening to podcasts/audiobooks.

Search and cultivate ideas.
Go to seminars and training, listen to podcasts while in traffic, read books before bed, and engage in conversations with people of substance. Make a habit of feeding your mind.

Capture the ideas in a journal.
Once you find something of value, write it down or record it, don't rely on your memory. Use a journal to capture the ideas that come your way. Start a new habit for wealth and happiness - the habit of journaling.
