Those things ensure you know the trades, can do the work. Self employed needs you to know how to bid the jobs, pay help and manage. Often the best builder is a failure as a self employed builder. A bad builder could run a crew of builders, different job with different skills to be the boss. So consider what has to be learned for being the boss.
