I am self employed for the last year or so, yet even before that I always felt that I worked for myself, that was what was important to me and if my efforts were to the benefit of another person/company than great, so be it but it would not be a driving force, to pay bills/family ? No.
For me it is so important to give it my all and enjoy the challenge, at the end of the day to go home with that self satisfaction, be it a good day or bad, knowing I did my best.
Then tomorrow I will be happy to do the same, it’s what works for me.
