We are not going to tell you that the secret ingredient is actually 'nothing' nor something like, 'belief'. What we are going to reveal is the truth, on how you can find your own ACTUAL secret ingredient. All we are going to provide to you are just, steps. Simple, steps. So brace yourself and get ready to take action!
1) Understand the concept of your recipe. What does your recipe focuses on? It would be much easier if you could find your own niche from the overly-wide topic. Determine that one simple idea and you're ready to go to the next step.
2) Use that particular idea, to find/test the correct material that you could use in your recipe. This is usually a little bit harder (eventhough we said it would be easy earlier) for you guys since, there is a very big possibility that the market outside has a wide range of product's selection to be chosen. Again, you will just have to keep trying to find the perfect one, but always remember, the better ones, are not usually the best ones.
Guess what? Two simple steps! That's all.
However, we would like to warn you that you will have to keep trying since the process for finding that secret ingredient might take a long time, a very long time indeed. So it is very important for you to not give up and keep doing the same thing as long as you don't lose your interest in it. You have to enjoy what you're doing, then only you know :).
