I've been a freelancer/contractor/solopreneur since 1974.

My advice...

Do freelance.

Don't work for one company. In other words, have many clients.

Be sure to arrange your hourly/ad-hoc work so it drives to some form of continuity.

Work hard, till you have your first $10K/month of continuity in place, then take stock of how to grow your business to the next level.
