The tendency is the most thing you love to do. If I gave you 1000$ with time off for a week, what will you do?
Will you fix your car? Travel? Buy video games? Invest? The thing that you will choose and love is your tendency.
To be creative, you need to learn. If you love something that nobody knows about, you can learn and deliver it in an easy way. For example, if you are a specialist in swords making and it is unknown, learn how to deliver information about it and start working.
However, if it is known, such as cars, try to learn more than anybody else through online videos for more than 18 hours a day for a month. You will see then that you understand more than someone who spent their life on cars.
Disappointment disappears with working. Work, and it will be gone!
