During a recent talk I explained the difference between the attitude of an employee and a self-employed person as follows:
As an employee you show up at work, do a good job, get paid and go home.
Imagine that instead, each time you showed up for work, you had to convince your employer to pay you, then you do your job and get paid and go home, having to repeat this each time you show up for work, with no guarantee that your employer will say yes. That is the life of a solopreneur.
To an employee, getting paid is a right.
To a solopreneur, getting paid is a privilege.
