I like the way you put the question, I can repay your modesty in valuable knowledge. Just making cathinones without giving any damn about the fact that you are dealing with organic synthesis which is a highly respected niche of preparative science I’m not sure it can make you proud of yourself... maybe satisfied with the income but then again if shit hits the fan... proving you are a competent chemist may shorten your sentence with several years to none (yes, been there done that).
