Affiliate Marketing Secrets

I am a beginner investor, but I am quite successful. I make around 5%-10% daily profit from my whole bank and rarely have a negative day. My secret probably relies on my bank management: I have extensive excel calculations that I gathered in 4 years of market study and even invented a profitable system myself.
My problem, though, relies on the withdraw of the profits. If I withdraw them, I will lose bank capacity to make more money in the long term. But if I never withdraw any, I will never really profit from my efforts.
When should I withdraw?
1) In a time basis (monthly for example)?
2) In a profit basis (Reaching for example 200% of the initial bank)?
How much should I withdraw?
3) A specific amount?
4) A percentage over the total bank?
5) A percentage over the initial bank?
6) Also, is there any formula for my answer, theoretically accepted by professional investors?
Thank you very much for your answers.

I have a marketing business, and have put a lot of time and work into my business. Our projected numbers were off, and it took a little bit longer than expected to get things up and running, so I need to go about finding an investor or venture capitalist. Does anyone have any ideas of how to go about this? We have a solid business plan laid out and a niche concept in our market and region. I would just love any advice that anyone could possible give me.
Thank you!

It’s a serious question.
I’m doing the obvious. I went to Uni, got a professional job, I save 50 percent of my net income(£1000 per month). I am studying the stock market, specifically options, in my spare time.
But what next…? I would love to know what a person could do instead of leaving their money in a bank (low interest rates). Mutual funds are vulnerable to market downturns; I’d prefer to be an active investor. I’m unsure of how to go about it – and thought I should learn from the best – you. You, the person reading this post, who have managed to create wealth.
We all know that there are too many people putting their hands out for money – whether to their bank or to their parents. What would be better is if people could learn from intelligent people like you who know how to make money.
So, please – let us know how you did it. How did you become wealthy? How did you know which businesses or stocks to invest in? Or did you find another route?
This is far better than “the secret millionaire” – instead of giving us a fish, I’m asking you to teach Yahoo readers HOW to fish!
