Capital can be in many forms. The time that you will spend to learn and grow your business is one of your main capital, even though no monetary capital but you need to invest human capital in your business. Each individual's time is precious, including you. The time that you will spend on growing your business is the time that you will spend less on other things such as leisure, family, academics.
I totally agree with you capital as we always look at shouldn't be only on monetary perspective most of the business that one don't put in money as capital take more energy time all a man need to even generate, there is saying that what deprived you of other things may be equivalent or even greater than those other things your deprived I think the effort made us another dimension of capital.
