Ask HN: What is something you do for clients that consistently blows them away?
Not a developer but love technology:
I began my organization skills by deconstructing simple BASIC games when BASIC was around as a pre-teen. 
Now, I'm hired to organize physical and electronic records, establish filing systems, workflows, and make physical records match the electronic records.<p>Create presentations that gather audiences' attention while not taking over from the speaker.<p>Desire to break into business analysis and have performed the work but not enough to make it official.<p>Past life created billing reports and client bills for a law firm. That took their THREE day billing process to less than one day on a sneakernet Access DBMS I designed.<p>Have also created feasible project and organizational budgets for humanitarian nonprofits.<p>Created an ad-hoc computer class for uneducated adults. Was told, "I've learned more with you in 15 minutes than a whole week at the community college." I purchased those computers for $4.00.
