If there are several responsibilities then it's very hard to collect capital by earning by yourself after fulfilling your responsibilities towards your families and get capital by your savings. Yes it is not so easy to get capital to start your own business but somehow you manage to get it from your close friends, and families then may capital helps to generate more revenue and individuals can uplift your  business on that level where they want. But if capital is not from your own savings then you must have to focus on your responsibilities with full focus to build your business successfully.
