However, how much passion you have for a task depends on you responsibly stoking the flames yourself – so to speak.
How feverish it is going to eat you up will depend on you too – how much time and effort you are putting into the task. If you do not put in the time and effort, you will lose it.
If you have no passion at all, find someone else who has the passion about what you are doing (or want to do) and learn from him/her.
Passion is contagious too – like most habits.
You stick around with someone who is passionate about what you want to master, and you will soon become passionate too.
(If you stick around with people who do not have the passion, your wish will slowly quiver over time into nothingness.)
When you have caught the passion from someone else, your responsibility is for you to spend time regularly to keep the fire burning, so to speak.
Your teacher will not be with you forever.
If you keep the passion up, you will pass it on to others who may want to follow the same path as you.
If you do not keep it up, you will lose it.
And the other aspiring people will not have the chance to catch it from you.
