@deprecated_ii There is a reason we do not teach babies to start running and jumping before they start walking. It is because they need to build up their coordination before they can do the more advanced things.
Granted, this is not the best direct comparison, but starting out at job such as fast food, a grocery store, or other simple things are like learning to walk. You can then later attempt running and jumping without worrying that you are "missing out" on "real skills."
