Yeah I agree as well. To me, that's the most important thing. If you don't enjoy what you're doing, then what's the point?!
Absolutely. Furthermore, though I hope will never loose self-motivation, I have realized, that it is really easy to be constantly tired. There is always next big something to catch up. That's why it is sooo important to really enjoy the big picture of what one is doing.
It's true! I hope you (and all of us) always love what we do and keep the self-motivation safe with us. Wish you good luck with your business whatever you do and wherever you are :)
