When Does the Cost of Success Become Too High?Work-life balance is not a simple equation. It's more like nuclear physics.

Iwrote recentlyabout life being like an investment portfolio. Well, if my life were an investment portfolio, you can compare last week to Bitcoin's recentcrash. Like so many professionals at some point in their careers, my personal life fell on its head, and the mess threatened to spill over into the business.

Simone Bilesmade headlines最近,当她退出了奥运会to focus on her mental health. Then, Ben Stokesdid the same. I wish I could take time off by choice. As a one-man show, "taking a personal day" when I have a lot of new business is not an option.

New clients are like a first date, and first impressions last.

The other side of Steve Jobs

I finished readingSmall Frylast week, by Lisa Brennan-Jobs, Steve Jobs's first daughter — although hedenied the relationship for years.

I never knew this part of Steve Jobs's life. His alleged cruelty to his daughter shocked the hell out of me. He has attained almostlegendary statusin the business world and is the go-to figure for countless articles featuringsage business advice,lifestyle choicesandpithy quotesthat have become part of the entrepreneurial canon.

I was aware that the book might beone-sided. So I decided to read Jobs's authorized biography by Walter Isaacson next, for which he gave the writer dozens of interviews.

The book confirms a lot of what Brennan-Jobs wrote.

So, the man could be cruel and spiteful and bitter and petty — but I know thatmylife has been improved remarkably because of him. I likely wouldn't even be a writer today if he had not carried out his vision!

Liking your work versus loving your work

I get asked the following question a lot: "So, I just wanted to check if youlikedoing this kind of project and if you'd be willing to take on the job?"

I usually respond that I like doing whatever pays the bills.

Butlikingwork andlovingwork are two different beasts. And they have wildly different effects on my state of mind.

Work that I likedistractsme. But work that I loveupliftsme.

When I do work that Ilike, I think of how it will pay for things for my daughter. When I do work Ilove, such asghostwritinga particularly moving memoir, I believe in my heart that the world might become a better place for her because of it.

Books change minds, and the best books change the world.

Did Steve Jobs think this way when he left his daughter every night to go into his office and work instead of spending time with her? If we ask two people about whether he did the right thing by spending so much time on the work he loved, we'll get two different answers.

In Brennan-Jobs's book, she reveals a scene of her father apologizing to her on his deathbed, weeping.

But would he have acted differently if given the chance?

The life-work balance equation is a farce

The equation I use for burying myself in my work is that "work = money for my family." If I don't build my business, they'll suffer, right?

But do they not suffer equally if I'm not there when they need me?

This is the constant struggle that professionals and entrepreneurs must face in their lives. And I think there is no simple answer.

The life-work balance equation isn't an easy X + Y = Z. It's more like those nuclear-physics equations that run for pages and pages, but also with constantly changing variables. And for those of us who are parents, choosing between our kids' soccer games and a mega-huge deal is an equation that carries terribly confusing weights on either side.

We read stories of people who quit their jobs to raise a family, and these stories are both praised and criticized. But who are we to judge what other people consider the right work-life balance forthemselves?

I remember a conversation I had with a lead once. He was offering me a lot of work, but my son was due to be born any day. I said, "Look, if my kid is born, I can't take the job on."

He said, "Paulo, uhm, congratulations, but I need the work done. And I'll go to someone else if you can't do it."

He isn't a father.

I told him, "Sorry, if my son is born, your project waits. Take it or leave it."

He took it.

And he became my biggest client.

But if I had been in a more difficult financial position, I might not have been so confident.

Work-life choices have a lot to do with the moment they're taken in. A choice made today might not be the right choice tomorrow.

Reading about Steve Jobs's life is interesting because he was a public figure who touched us all. But tojudgehim as "success" or "failure" is impossible — and it isn't our place either. He made his choices, and he was the one who had to live with them.

For me, work-life balance is simply this: doing the best I can do in the moment and trusting myself to do better next time if I make a mistake. In the end, I know that I will judge my own life harder than anyone else will.
