Is your true professional passion and 'true north' to be in business? Or. would you rather be doing something else - be an engineer, doctor, artist, etc?
Desire is the need to possess or achieve something. If you desire something, you will seek the internal and external motivation to achieve it. Intrinsic motivations could be things like seeking prestige, wealth, financial independence or power. Extrinsic motivations could be things like wanting to please somebody, beat a competitor or acquire something. Is being in business aligned with your 'true north' - what you enjoy doing?
If you have the desire and motivation to be in business, are you committed to sticking with it n spite of setbacks that most people invariably encounter?
