Know your strengths, in other words, skills, and keep them sharp, always be honest with yourself so you do not go for projects beyond your skill level. Reputation is everything. The journey is not a bed of roses especially if you're just getting started. It takes time, sweat and dedication to build a client base to the extent where you do not even need to apply for projects and instead rely upon the relationship with various studios/clients you'd build overtime. Build your portfolio, if you can't get paid work, help out those non profit organizations do whatever it takes to build a portfolio. Try various freelancing platforms, stick to those that work for you.
Good luck!
