(Heck, I wish there were fewer parties, like if five single-topic good parties (bij1 against racism, pirate party for internet freedoms, volt for international collaboration, party animals for environmental welfare, etc., plus greenworkersparty as the current overarching big boy) would band together, it'd be a much easier choice!)
That not every country is so lucky (not all of them have free elections, or elections at all) is a shame indeed, but at least for countries like mine I'd be much happier to have a government arrange a system than a tech corporation and foreign laws. Presuming that the 2-party system you speak of is the USA's, at least both corps are governed by your own laws, that's something!
What's harder?
Convincing enough people to matter (in some kind of election-based system) to get behind your platform - either with you as a candidate, or working to promote a candidate or party or movement that you do believe in.
People talk like their changemaking ideas are very widely held - the way people talk it's like they believe 75%+ of the country must actually agree with them - but then they don't run for office on such a popular platform that it should be a sure election win, yes even with countervailing forces such as electoral college, Senate, etc.
