This is unfortunately down to two things.
1....School fees (your mistakes you WILL make despite what every one tells you) and
2....your ability to control your emotions when investing/trading.
You also have to decide trader or investor or a bit of both. Trader buys sells often (as little as 3 times a year and as much as 10 times a day or more), Investor buys and holds long term (5 years plus)
combination is using some capital to trade and some to invest.
Then lastly attend all the courses offered at least twice (the first time you will be "wowed and enlightened", the scond you will actually take it in and remember)
And absolutley final, your experienece, this takes time and dedication. Your trouble early on I have seen is lack of dedication. Jumping between two careers in two years points to your itchyness to often be pushed and challenged, sometimes the best thing to do is to do nothing.... OMO though and no offence ment.
