How do you know when you're on the right career path?

I have had a diverse range of experience. I studied advertising then property development at uni. My first entrepreneurial business venture was running events, I did this through uni and did pretty well. I then launched an e-commerce store which I sold. I now work for a property development company to learn as much as possible, I am a partner in a hiring and recruitment company and am doing my own property development project of 4 townhouses. I am 26. Working at the property development company has been very good, it's been difficult being an employee but i am learning a lot. I spend my nights and weekends hustling. I now understand how a big business operates. My bosses business has generated around 5 billion in revenue. Long-term, I'd love to focus on property development but I also love business in general. You need a lot of funds or backing for property development so I've been leveraging all my financial streams to date to reinvest into real estate projects. How do you know when you are on the right path? What questions do you ask yourself? How do people run more than one business usually in an effective way?
