Should I start a business?
Weigh your runway, your evidence, and your appetite for risk before you hand in notice or sign a lease.
Maybe the idea has been following you around for months, or maybe a bad week at work just made it feel urgent. Either way, starting a business is one of those choices that feels enormous because it touches everything at once: your money, your identity, your time, and often the people who depend on you. It is completely normal to swing between excitement and dread several times a day.
This page is meant to slow that swing down. First, score your own situation in the free decision matrix below: adjust the weights so they reflect what matters most to you, then rate both options on each criterion. After that, read the guide, which covers the questions worth asking yourself, the signs that point each way, common mistakes, and the middle path many founders actually take.
Six questions to ask yourself
Which way is it pointing?
Signs you're ready to start
- People have already paid you, preordered, or committed in writing.
- You could cover at least six months of household expenses from savings or a partner's income.
- You've run a small version on the side and want to do more of it, not less.
- You can describe your first customers, how you'll reach them, and what they'll pay.
- Your household has talked through the downside and agreed to it, not just tolerated it.
Signs waiting may be smarter
- Your plan only works if the business replaces your salary within a few months.
- You haven't talked to potential customers outside your circle of friends and family.
- You're carrying high-interest debt or have no emergency fund.
- The main appeal is escaping your current job rather than building this particular thing.
- A major life change, such as a new baby or a move, is already taking most of your energy.
Evidence worth knowing
Founders who kept their day job while starting a business had a lower risk of failure, roughly one-third lower, than those who quit outright to go all in.
Raffiee & Feng (2014), Academy of Management JournalIn the short term, people tend to regret things they did. Over the long run, they more often regret the things they didn't do.
Gilovich & Medvec (1995), Psychological ReviewPeople predicted how they would feel about an upcoming experience more accurately from another person's report of actually living it than from their own imagination. Talking to people who run a similar business is worth the effort.

Leaving your job to go all in before anyone has paid you removes your safety net at the moment you know the least. Validate first, then scale up your commitment.
Revenue usually arrives more slowly than founders hope. Build your runway around a slower timeline than your spreadsheet suggests.
Health insurance, self-employment tax, retirement savings, software, and licenses all become your responsibility. Price them for your state and add them to your budget before you leave.
A partner or family absorbs much of the risk, so they deserve a real say. A few honest conversations with people who have started something similar can also save you expensive surprises.
The option people forget
The option people often forget is the hybrid start: keep your job, or move to part-time or contract work, and build the business in protected hours such as evenings, weekends, or one negotiated day a week. Set a clear trigger for going full time, like a specific monthly revenue level held for several months or a set number of repeat clients. You trade some speed for safety, but you gather real evidence before putting your income on the line. Check your employment contract for moonlighting or non-compete clauses first.
The Decision Engine
If you're comparing more than two paths, such as launching now, starting on the side, or freelancing first, The Decision Engine ($19) lets you weigh up to five options against your own criteria, run the 10-10-10 test and a coin-flip gut check, and save a printable report to revisit as things change.
Questions people ask
How much money should I save before starting a business?
A common rule of thumb is 6–12 months of personal living expenses, kept separate from whatever the business itself needs to launch. The right number depends on your fixed costs, your household's other income, and how quickly your type of business tends to earn. This isn't financial advice; an accountant or fee-only financial planner can help you work out a figure for your specific situation.
Should I quit my job to start a business?
Not necessarily, and often not right away. Many founders start on the side and leave only once the business shows consistent revenue. If your idea genuinely can't be tested part-time, make sure your savings and a fallback plan are in place before you resign.
What happens if my business fails?
Plenty of people who close a business return to employment with new skills, contacts, and a clearer sense of what they want. The real danger is a failure that takes your savings or home with it. Limit personal guarantees, keep business and personal finances separate, and decide in advance how much you're willing to lose.
Am I too old or too young to start a business?
Circumstances matter more than age. Older founders often bring experience, networks, and savings, while younger ones often have fewer obligations and more time to recover from a setback. Focus on your runway, your dependents, and your evidence of demand rather than your birth year.
