Elon Musk: Work twice as hard as others

3 Pieces of Advice for Entrepreneurs from Billionaire Elon Musk

1) Being focused on something that your confident will add high value to someone else - be rigorous in making that assessment. The challenge is knowing what's the difference between your ideals and sticking to them versus pursuing some unrealistic dream that doesn't actually have merit. Can you tell the difference between those 2 things.

2) Be tenacious

3) Work like hell! Must put in 80-100 hour weeks every week! If you do 100 hour weeks and the other person does 40 hour work weeks you will achieve in 4 months what he/she will achieve in a year.
