Having A Had Time Starting Over

I've been thinking about how successful people find their thing, and I'm seeing two completely different patterns.

Some people just throw shit at the wall relentlessly. They're not waiting for the perfect idea, they're trying things, iterating, failing, trying again. They find niches and make something work through pure volume and persistence.

But then there's another set of successful people who aren't trying at all. They're just living their life, doing something they're genuinely interested in, and somehow an idea finds them. They see an opportunity, they jump on it, and it works.

Here's where I'm stuck: I’ve had 3 business now that didn’t work out for many different reasons. The biggest issue is that they were a losing game from the start (I obviously didn’t know). I decided I need to switch paths and find a new niche. I’ve spent the last 6 months trying all sorts of things and brain storming new ideas, so far nothing has really hit it off. I feel like I should stop searching for the perfect idea and just focus on a new hobby. But that feels like I'm wasting time.

My full time engineering job is a dead end (and no I can’t just go and find a more interesting job. The job market here in Canada is terrible and I’m lucky to have a job at all).

All I want is to start a business and escape this situation. But I'm paralyzed because I can see both paths working yet neither has worked for me. Some people grind their way out by never stopping. Others just live their life and opportunity finds them. And to me, doing nothing feels like a waste of time that won't get me out. At the same time, doing as much as possible has gotten me no where.

What really pisses me off is that a lot of advice online when looking to start a business is that people are un motivated and lazy. A lot of the videos just talk about getting people to take the chance and go for it. I am the complete opposite. I am more hungry than ever but yet I am being starved of opportunity. No matter how hard I try I can’t find something to go after. Constant dead ends or failure.

I'm really conflicted and could use some perspective on this.

Edit: My issue is that I need to find a new niche and I don’t know how. The niche of my last 2 business is not something I wish to continue to explore. This is why im having a hard time finding a new business idea.
