To work the top class you’ve got to be in top condition and you’ve got to be prepared. No sportsman would ignore training and strategy. Don’t ignore these when it comes to business either.
If you are genuinely scared of the outcome of your marketing because you have just randomly tried to market your product to some people who probably are not even your target customers, then you’re quite rightly scared.
Remember, first set your goal and then find your way towards it. Don’t try any random route without knowing where you want to get. Chances are, you’ll miss that place – no matter how tough your mind is.
