It seems to me that most people who have that 'there has to be more to life than this' feeling (later: the feeling) are those who are also stuck in a 9-to-5 job they hate but do to pay the bills. It sounds almost like the feeling is theirs - that you can't have that feeling if you're an entrepreneur, or an artist, or unemployed, or a student. Whatever you're feeling, it's not that, because they own it.
Newsflash: I don't exactly agree with this idea.
Or better yet: this idea is a truckload of bull crap.
Anyone, anyone, regardless of circumstances, can feel the feeling. Even if you're your own boss, or even if you don't have a boss. The way I see it, there can be two reasons to the feeling:
- You don't see meaning in what you do.
- ...actually, that first one perfectly encompasses every reason there is.
So if you have a 9-to-5 or a 12-to-4 or whatever-time-stamp job, and you don't see meaning in it - even if you don't hate it per se - you can have the feeling. However, you can also have the feeling if you're in your dream job, whatever that may be, if there's something in what you do that needs some adjusting. It can be a small thing. But most likely, it's something big.
For example, if you're an entrepreneur, and you don't work enough, the lack of work - the time you spend doing anything but work - can consume you and make you think life should be more than this. It's a natural response. Your mind, by giving you the feeling, wants you to do more of that which brings meaning.
Create principles regarding and surrounding your meaningful work, and honor them.
