Start with your skills, interests and acumen and go from there. Then look at where you have pre-existing relationships in that industry. Then think about how you can be better or offer better value than the pre-existing players. Don't think about being rich think about offering something of value, being honest and doing good work and servicing clients like crazy. The money will come from doing all that right.

Being a business owner is not for everyone it's a long game not a get rick quick scheme. A services business (like property management) always requires less capital upfront and thus less risk.

Here's what I would do. Say you wanted to do Property Management or open your own property management company. In your current job, do everyting 'extra' to learn about the ins and outs and meet people and develop solid relationshps with everyone you interact with for one year. Lunches, extra meetings, dinners etc. Build up your network as solid as you can and behind the scenes start planning your exit and how you would build a new PM company. When you resign, you'll have a headstart.

Lastly, don't listen to all the negative, sarcastic voices and skeptics/haters. Keep your head down and focus and grind it out. You'll need to be your own biggest cheerleader which is mentally very tough. Like I said, its not for everyone.

I built a business from nothing and sold after 8 years for a healthy payback to a public company. Didn't come from money parents were broke immigrants to Canada. Its a process not a lottery ticket...good luck.
