The best way to make the change is to not do it. Put that extra trading time and effort into your job. You will be 1000x happier 10 years from now.
If your not interested in trading the off hour products you are limited in getting the hands on practice that most need. However it doesnt eliminate you from the business side setup of launching your career. Incorporate, Build assets, leverage assets up. Then once your confident in your trading skills/diversification then make the jump. Keep growing the business until it's big enough to walk away from JOB.
