Start accumulating more trading capital now. Your first objective is to make your trading capital last through the learning process. Most people do not meet this test. You will therefore probably require more capital than you anticipate. On the other hand, starting small is a great way to reduce your risk, learn to trade with smaller positions and build up some confidence, before you enter a more demanding environment.
Most traders do start small, because it makes sense.
It can be done. I know several people who have become successful at trading. Read published interviews of these traders. All of the traders I know do not consider it an easy stress-free source of instant riches. They treat it as a serious business because they are trading with real money.
