Entrepreneurs are usually self-motivated and self-confident and they love a challenge. would you describe yourself this way?

Yes the statement is True.

Explanation:

Entrepreneurs are people who start their own business, bear all cost of setting up the business in the hope of getting profits out of it. Starting a new business by a single person on his own is such a big decision. Such decisions need high confidence and courage. Also higher level of motivation is also needed, because if the person who is starting a new business is not motivated enough, he won't be able to proceed further in his business if any obstacle comes in the way. So this is so true that Entrepreneurs are self motivated and self confident and they love challenges.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
