That's the advice I do give to newbies. Operate from the area of your core competence and you will add value to yourself and the forum. If only Op actually possess that skill, it will be helpful to him.
But I was skeptical about that skill when I saw the question that shouldn't have been asked.
There are many people who claim to have qualified skills in certain fields,
but it is only camouflage and only understands the basics, not really understanding it well.
I know some people who understand data analysis very well, and they do it well, get more merit and are very useful for the forum.
In fact, they started from a Newbie account, which then in a short time could rise in rank more easily.
The OP should have done that if he had the skill as a data analyst,.
