Passion + Business
When, you do what you love! You will have the zeal to do whatever it takes to be successful. Stay up long hours, put in the extra effort to get things done in a timely manner. When you have passion for something, it doesn't feel like work.
People who love what they do, tend to be more happy with their business. They may not make millions of dollars doing what they love but the mere fact that...they are doing what they love. It brings happiness, joy - they feel whole and at peace. That is a wonderful feeling. So, when you find something you are passionate and good at - that can be profitable. Educate yourself more about that field and GO for it. It will be the best decision you will have made for yourself. Your future self will THANK YOU! :)
