First Answer: None.

Second Answer: It Depends.

When making a necessary change, like deciding to go on a run or workout regularly, the resulting feeling of well-being is immediate. The feeling of relief is almost tangible.

Such is the reason why patience and grabbing on to that immediate feeling is so important.
