Write this method in user model

def wishes_count counter = 0 lists.each do |list| counter += list.wishes.count counter end 

Howdy {Username}, you have made <%=h @user.list.count %> lists, and <%=h @user.wishes_count %> wishes

you can't use @user.wishes.count since user is not directly related to wishes, hope this solution works for you. If any questions please drop a comment.
