I would do idea #1 in a stable career that pays well. Collect a nice Friday paycheck and transition to do flight instruction on the weekend. Later on in life is a good time to do flying full time if the dice roll right and it is still in your plans. By that time you should have saved some of that money earned earlier to help ease the transition. If you ever need to go back doing what you did earlier for any reason (i.e. aviation slowdown, medical, personal) there should hopefully be some relief.
