Financial freedom is a mindset and an approach to money where you always have more than you need. The way you achieve that is to spend less than you earn. Someone can be financially free working at a café.
I would radically reduce your spending to what is actually needed, to reduce pressure from quitting your job. Forget about being rich from quitting your 9-5 and realize you can be happier with less money. You can be happy without new clothes, a car, Netflix subscriptions, eating out, video games, etc.
If you want to freelance, my most effective strategy to acquire clients was to email startups looking for full time engineers and offer to do contract work for slightly lower rates on my own terms. Worked especially well for startups that had listings open for more than a few months. Most startups can’t afford decent engineers, so take advantage. That’s what I would do without a network.
If you have the skills you can find clients. Research freelancing. Be proactive. Take action. You will see results.
