Unfortunately you don't have track records of the various advisers, so you may as well try to do it your own way.
I would say it's important to preserve the capital while learning (no capital = no trading), so it would be less painful if you stick to strict rules. Maybe if you limit your potential losses to 0.5% max per trade, 1% max per day, 2% max per week, 5% max per month etc. This is just an idea - you can use your own figures - just try to imagine what would it feel like if you suffered that kind of losses and adjust them accordingly.
PS If the amount you can afford to lose is £10,000 - 0.5% would be £50. Are you OK with losing £50 per trade or £100 per day or £200 per week or £500 per month? Also can you afford to lose £10,000 without adverse affects on your standard of living?
If not, you should think about some other figures or maybe try to open a demo account.
Can you follow the rules i.e. stop trading once the loss reached predefined daily, weekly or monthly level? If not you shouldn't use real money.
It is a slow, boring and demanding process to make it from loser to winner. The other way round is much quicker.
