Never sell yourself short.And if you are good at something ,never do it for free.
Reminds me of a fav.story of mine.
A man went to a doctor and said his leg hurts a lot.The doctor examined him thoroughly and then took a small orthopaedic hammer.
He fixed a point on the knee and hit him with the hammer lightly there.
Behold! the pain was gone!
The patient asked how much the fee was.
The doctor said -a thousand bucks!
The patient was incredulous."A thousand for hitting a hammer on the knee?!"
The doctor replied:"10 bucks for the hammer hit.990 bucks for knowing where to hit and how hard.!!"
So.Skill costs.The big pockets specially must realize that.Dont be a Shylock.But never sell yourself short.
