A Parent's thoughts on time vs money

As a parent, I want to give the best to my children. And as much as I could, to provide them with the opportunities and exposures. Undoubtedly, money gives one a higher chance of accessing resources, beneficial to giving my kids a head start in future. With this belief, I persevered in my current job, where I spend about 30% of my time out of the country, away from my young children. 

With the money I get out of my job, I outsourced childcare to childcare centres (so that I can continue working). When I am overseas, my partner looks after the kids at night, outsourcing childcare to TV when it becomes unmanageable. 

Have my kids benefited from the my fruit of labor at work (aka money)?

What have I benefited from the relentless work?

Is the cash gained from this job really worth the sacrifice?

If I derive joy from joy from my job, gain valuable experience, perhaps it's worth it. But, what if the job just becomes a transaction between time and money?

I'm leaving my current job, without plans for next. To many, they may say it's an irresponsible plan for a parent. But to me, this is one of the most responsible thing I'm going to do for my children.

While this is the first time since after graduation when I live without a pay, I have enough buffer. Living frugally, this could last me some time.
