Not all. Life is not Marry Poppins 24/7.
Your perspective is great as long as it takes into account the fact that getting good at something, or achieving a major accomplishment, requires a lot of hard work - and that hard work is worth doing, even when setbacks and difficulties are encountered.
Effective, long-term hard work is most often done successfully by people who are enjoying a lot of it. Don't try to achieve mastery in a field you dislike!
For me, I have realized that I need to do many things that are hard/boring, and the key to motivating this action is by focusing on the completed product (“looking forward to where I’m going”) as opposed to enjoying every second of the activity (“moment by moment satisfaction”).
