How do I start a startup?

I'm a technical guy with all the necessary technical knowledge and a brilliant idea in my mind.

I'm kind of stuck in personal and professional life so much that I'm litelly not able to think of taking a step further for bringing my startup idea into reality.

I'm literally forced to take a short lived time off just for being me and am never able to initiate my efforts for my startup.

Lately I've tried getting some time by skipping my ofc calls and skipping family meet ups. But still need a better way.

Does anyone have any better way to tackle this problem in a better way?

Note: I've let go of most of the social media applications.
