Every industry that needs serious attention and training in order to access means that there are gatekeepers; sometimes the gatekeepers are expensive and/or abusive.
Attention means energy; if you're exhausted from whatever job, you may not have the energy.
Attention means time; if you're spending more than 35-40 hours a week working, you've still got housework and such, and time you spend to understand things is time you're not actively earning, even if it may pay off later.
