What do you think of musicians that still have daytime job?

thanks for all the replies for my previous questions, now I have clearer picture of what I have to decide to do. although I still have one nagging question/issue, and this is what I want to ask all of you:

we all know that music is not an easy world.
often there’s a hell lot of sacrifices to make, a thing which i’ve learned now.
whether it’s a stable living, or money, or family-relationship, or at the very extreme, the risk of being lonely poor broke musician!
that’s the risk that ANY musician (or a person who’s still have high passion & ideals in music) has to take.

so as a ‘cushion’ to all of these dangerous risks, you’ve probably met & found many musicians who still want to keep the “safe zone” by having daytime jobs, usually even not related with their passion, Music.

now, what do you think of musicians that still have daytime jobs like this?
do you thinks it’s a bit ironic somewhat?
i mean, think about it, you’ll probably never see a person whose passion or dreams to become a lawyer, or doctor, having ANOTHER non-related job as their “daytime job” .
but only in music (or rather, Art), that you’ll find many cases/stories like this where a passionate-musician, unfortunately (or ironically), have to “make a living” NOT through their utmost passion, but in fact, perhaps through a job that they DISLIKE (or even hate), just in order to keep-up with their REAL passion in Music, in their SIDE-time? (notice all my emphasis)

in an ideal world, i know that these so-called musicians probably would prefer to have Music as their ultimate FULL-time job, rather than only as their ‘side-time’ job, while have to work in non-music-related daytime job.
but alas, we all know that the world we’re living is mainly geared towards Money, and thus, a musician even has to be very ‘practical’ about their life, like it or not!

do you think these musicians live ‘painfully’ (ie: not too happy) while enduring their daytime jobs at the noon? while dreaming WHEN they can really take Music as their primary full-time job?
or they are actually quite happy even while doing music (ie: gigging, touring, producing) during their side(free)-time?
